### Ratio and Proportion Class 6 Worksheet Solutions

Ratio and Proportion Class 6 Worksheet – Solution 1

HCF of 12 and 60 is 12
Since, 12 : 60
= $\cfrac{12}{60}$
Dividing Both 12 and 60 by their HCF
= $\cfrac{12 \div 12 }{60 \div 12 }$
= $\cfrac{1}{5}$
= 1 : 5
Hence, the simplest form of 12 : 60 is 1 : 5

Correct Answer – d) 1 : 5

Ratio and Proportion Class 6 Worksheet – Solution 2

Taking both the quantities in same unit, we have
2.5 m = ( 2.5 x 100 ) = 250 cm
The equation now becomes, 60 cm : 250 cm
or
= $\cfrac{60}{250}$
Dividing both the numbers by their HCF, i.e
= $\cfrac{60 \div 10 }{250 \div 10 }$
= $\cfrac{6}{25}$= 6 : 25
Hence, the required ratio is 6 : 25

Correct Answer – d) 6 : 25

Ratio and Proportion Class 6 Worksheet – Solution 3

Taking both the quantities in same unit, we have
2 kg = ( 2 x 1000 ) = 2000 g
The equation now becomes 50 g : 2000 g
or
= $\cfrac{50}{2000}$
Dividing both the numbers by their HCF, i.e 50
= $\cfrac{50 \div 50 }{2000 \div 50 }$
= $\cfrac{1}{40}$= 1 : 40
Hence, the required ratio is 1 : 40

Correct Answer – a) 1 : 40

Ratio and Proportion Class 6 Worksheet – Solution 4

Taking both the quantities in same unit, we have
3 hours = ( 3 x 60 ) = 180 min
The equation now becomes 30 min : 180 min
or
= $\cfrac{30}{180}$
Dividing both the numbers by their HCF, i.e 30
= $\cfrac{30 \div 30 }{180 \div 30 }$
= $\cfrac{1}{6}$= 1 : 6
Hence, the required ratio is 1 : 6

Correct Answer – c) 1 : 6

Ratio and Proportion Class 6 Worksheet – Solution 5

Taking both the quantities in same unit, we have
₹ 1.5 = ( 1.5 x 100 ) = 150 paise
The equation now becomes 75 paise : 150 paise
or
= $\cfrac{75}{150}$
Dividing both the numbers by their HCF, i.e 75
= $\cfrac{75 \div 75 }{150 \div 75 }$
= $\cfrac{1}{2}$= 1 : 2
Hence, the required ratio is 1 : 2

Correct Answer – d) 1 : 2

Ratio and Proportion Class 6 Worksheet – Solution 6

On multiplying or dividing each term of a ratio by the same non zero number, we get a ratio equivalent to the given ratio
For, $\cfrac{20}{16}$
Both numerator and denominator of given fraction is multiplied by same nonzero number i.e 4
$\cfrac {5\times 4 }{ 4\times 4 }$ = $\cfrac{20}{16}$
$\cfrac{20}{16}$is an equivalent ratio of $\cfrac{5}{4}$
$\cfrac{4}{5}$is not an equivalent ratio of $\cfrac{5}{4}$As both 5 and 4 are not multiply by same non zero number
$\cfrac{21}{12}$is not an equivalent ratio of $\cfrac{5}{4}$As both 5 and 4 are not multiply by same non zero number
$\cfrac{18}{12}$is not an equivalent ratio of $\cfrac{5}{4}$As both 5 and 4 are not multiply by same non zero number

Correct Answer – c) $\cfrac{20}{16}$

Ratio and Proportion Class 6 Worksheet – Solution 7

Let the required number be 2a and 3a
Since the sum of these two numbers is given, we can say that
2a + 3a = 75
5a = 75
a = $\cfrac{75}{5}$
a = 15
So, the first number is 2a = 2 x 15
= 30
Second number is 3a = 3 x 15
= 45
Hence, two numbers are 30 and 45

Correct Answer – a) 30 and 45

Ratio and Proportion Class 6 Worksheet – Solution 8

Total money = ₹ 4500
Given ratio = 3 : 2
Sum of ratio terms = ( 3 + 2 )
= 5
Give: $\cfrac{3}{5}$part of ₹ 4500 to X
Give: $\cfrac{2}{5}$part of ₹ 4500 to Y
that is,
X ‘s share = ₹ ( 4500 x $\cfrac{3}{5}$) = ₹ 2700
Y ‘s share = ₹ ( 4500 x $\cfrac{2}{5}$) = ₹ 1800

Correct Answer – c) X = 2700 , Y = 1800

Ratio and Proportion Class 6 Worksheet – Solution 9

Total money = ₹ 1800
Given ratio = 3 : 4 : 1
Sum of ratio terms = ( 3 + 4 + 1 )
= 8
X share = ₹ ( 1800 x $\cfrac{3}{8}$) = ₹ 675
Y share = ₹ ( 1800 x $\cfrac{4}{8}$) = ₹ 900
Z share = ₹ ( 1800 x $\cfrac{1}{8}$) = ₹ 225

Correct Answer – a) X = 675 , Y = 900 , Z = 225

Ratio and Proportion Class 6 Worksheet – Solution 10

We can write
( 2 : 1 ) = $\cfrac{2}{1}$ and ( 1 : 4 ) = $\cfrac{1}{4}$
Now, let us compare $\cfrac{2}{1}$ and $\cfrac{1}{4}$
LCM of 1 and 4 is 4
Making the denominator of each fraction equal to 4
We have, $\cfrac{2}{1}$ = $\cfrac { 2 \times 4 }{ 1\times 4 }$ = $\cfrac{8}{4}$
and $\cfrac{1}{4}$ = $\cfrac { 1 \times 1 }{ 4\times 1 }$ = $\cfrac{1}{4}$
In case of Like fractions, the number whose numerator is greater is larger. Hence we can say $\cfrac{8}{4}$ > $\cfrac{1}{4}$
That is $\cfrac{2}{1}$ > $\cfrac{1}{4}$
Hence, ( 2 : 1 ) > ( 1 : 4 )

Correct Answer – a) ( 2 : 1 ) > ( 1 : 4 )

Ratio and Proportion Class 6 Worksheet – Solution 11

Let $\cfrac{4}{7}$ = $\cfrac{y}{35}$
Then, 4 x 35 = 7y
7y = 4 x 35
y = $\cfrac{4\quad \times \quad35 }{7}$
y = 20
Hence, $\cfrac{4}{7}$ = $\cfrac{20}{35}$

Ratio and Proportion Class 6 Worksheet – Solution 12

Let $\cfrac{56}{104}$ = $\cfrac{y}{13}$
Then, 56 x 13 = 104y
104y = 56 x 13
y = $\cfrac{56 \times 13 }{104}$
y = 7
Since, $\cfrac{56}{104}$ = $\cfrac{7}{13}$
Again, let $\cfrac{7}{13}$ = $\cfrac{14}{z}$
Then, 7z = 14 x 13
z = $\cfrac{14 \times 13 }{7}$
z = $\cfrac{182}{7}$
z = 26
Since, $\cfrac{7}{13}$ = $\cfrac{14}{26}$
Hence, $\cfrac{56}{104}$ = $\cfrac{7}{13}$ = $\cfrac{14}{26}$

Correct Answer – a) 7 , 26

Ratio and Proportion Class 6 Worksheet – Solution 13

We have 90 cm : 180 cm
= 90 : 180
= $\cfrac{90}{180}$
=$\cfrac{90 \div 90 }{180 \div 90 }$(HCF of 90 and 180 is 90 )
= $\cfrac{1}{2}$
180 m : 340 m
= 180 : 340
= $\cfrac{180}{340}$
=$\cfrac{180 \div 20 }{340 \div 20 }$( HCF of 180 and 340 is 20 )
= $\cfrac{9}{17}$
Since, the ratios 90 cm : 180 cm and 180 m : 340 m are equal to $\cfrac{1}{2}$ and $\cfrac{9}{17}$ . So, they are not in proportion.

Ratio and Proportion Class 6 Worksheet – Solution 14

We have, 6 : 9 = $\cfrac{6}{9}$ = $\cfrac{6 \div 3 }{9 \div 3 }$= $\cfrac{2}{3}$
and 10 : 15 = $\cfrac{10}{15}$ = $\cfrac{10 \div 5 }{15 \div 5 }$= $\cfrac{2}{3}$
Since, 6 : 9 = 10 : 15
Hence, 6 , 9 , 10 , 15 are in Proportion
Alternative method: Product of extremes = Product of means
Here, Means are 9 and 10
Extremes are 6 and 15
Product of extremes = 6 x 15 = 90
Product of means = 9 x 10 = 90
Since, Product of extremes = Product of means
Hence, 6 , 9 , 10 , 15 are in Proportion

Ratio and Proportion Class 6 Worksheet – Solution 15

We know that, Product of means = Product of extremes
In the given numbers, we can say that 4 , y are means and 2 , 6 are extremes
4 x y = 2 x 6
y = $\cfrac{2\quad \times \quad6 }{4}$
y = 3
Hence, y = 3

Ratio and Proportion Class 6 Worksheet – Solution 16

Clearly, Product of means = Product of extremes
y x y = 4 x 16
${ y }^{ 2 }$ = 4 x 16
${ y }^{ 2 }$ = 64
Hence, y = 8

Ratio and Proportion Class 6 Worksheet – Solution 17

2 , 12 , y are in proportion
Which means 2 , 12 , 12 , y are in proportion
i.e, 2 : 12 : : 12 : y
Product of means = Product of extremes
here,
means = 12 and 12
extremes = 2 and y
12 x 12 = 2 x y
144 = 2 x y
y = $\cfrac{144}{2}$
Hence, y = 72

Ratio and Proportion Class 6 Worksheet – Solution 18

$\cfrac { Number\quad of\quad \quad boys }{ Number\quad of\quad girls}$ = $\cfrac{75}{45}$
On simplifying,
$\cfrac { Number\quad of\quad \quad boys }{ Number\quad of\quad girls}$ = $\cfrac{75 \div 15 }{45 \div 15 }$( HCF of 75 and 45 is 15 )
= $\cfrac{5}{3}$= 5 : 3
Hence,the ratio is 5 : 3

Correct Answer – b) 5 : 3

Ratio and Proportion Class 6 Worksheet – Solution 19

Clearly, less workers will take the more days.
And, more workers will take less days.
8 workers can reap a field in = 12 days
1 worker can reap a field in = ( 12 x 8 ) days
Hence, 4 workers can reap a field in = $\cfrac{12 \times 8 }{4}$days = 24 days
Hence, 4 workers can reap a field in 24 days

Correct Answer – c) 24 days
