Measuring Length Worksheets for Grade 3 Explanations
Q.1) Explanation – Measuring Length Worksheets for Grade 3
As we know that,
1 km = 1000 m
To find 5 km in m. We have to multiply both sides by 5
( 5 x 1 ) km = ( 5 x 1000 ) m
5 km = 5000 m
Q.2) Explanation – Measuring Length Worksheets for Grade 3
5 km 438 m can also be written as 5 km + 438 m
To change 5 km + 438 m into m
we have to convert 5 km in m
As we know that,
1 km = 1000 m
5 km = ( 5 x 1000 ) m
5 km = 5000 m
Therefore,
5 km + 438 m = 5000 m + 438 m
= 5438 m
Q.3) Explanation – Measuring Length Worksheets for Grade 3
As we know that,
1 km = 1000 m
or 1000 m = 1km
then,
1 m = 1/1000 km
To find 4000 m in km. We have to multiply both sides by 4000
( 4000 x 1 ) m = ( 4000 x 1/1000 )km
4000 m = 4 km
Q.4) Explanation – Measuring Length Worksheets for Grade 3
As we know that,
1 km = 1000 m
or 1000 m = 1 km
then,
1 m = 1/1000 km
To find 1865 km in km and m. We have to multiply both sides by 1865
( 1865 x 1 ) m = ( 1865 x 1/1000 )km
1865 m = 1.865 km
Digits before decimal point is written with kilometre ( km ) and after decimal point with metre ( m )
Hence, 1865 km = 1 km 865 m
Correct Answer – a) 1, 865
Q.5) Explanation – Measuring Length Worksheets for Grade 3
As we know that,
1 m = 100 cm
To find 7 m in cm. We have to multiply both sides by 7
( 7 x 1 ) m = ( 7 x 100 ) cm
7 m = 700 cm
Q.6) Explanation –Â
5 m 624 cm can also be written as 5 m + 624 cm
To change 5 m + 624 cm into cm
we have to convert 5 m in cm
As we know that,
1 m = 100 cm
5 m = ( 5 x 100 ) cm
5 m = 500 cm
Therefore,
5 m + 624 cm = 500 cm + 624 cm
= 1124 cm
Q.7) Explanation – Measuring Length Worksheets for Grade 3
As we know that,
1 m = 100 cm
or 100 cm = 1m
then,
1 cm = 1/100 m
To find 300 cm in m. We have to multiply both sides by 300
( 300 x 1 ) cm = ( 300 x 1/100 )m
300 cm = 3 m
Q.8) Explanation –Â
As we know that,
1 m = 100 cm
or 100 cm = 1 m
then,
1 cm = 1/100 m
To find 714 cm in m and cm. We have to multiply both sides by 714
( 714 x 1 ) cm = ( 714 x 1/100 )m
714 cm = 7.14 m
Digits before decimal point is written with metre ( m ) and after decimal point with centimetre ( cm )
Hence, 714 cm = 7 m 14 cm
Correct Answer – a) 7 , 14
Q.9) Explanation – Measuring Length Worksheets for Grade 3
Write Kilometres (km) and Metres (m) aligned in columns properly.
Add Kilometres (km) and Metres (m) as we add numbers in Addition.
Hence, the sum is 89 km 197 m
Correct Answer – b) 89 km 197 m
Q.10) Explanation –Â
Step I: Write m and cm aligned in columns properly.
Step II: Add Metres (m) and Centimetres (cm) as we add numbers in Addition.
Hence, the sum is 66 m 11 cm
Correct Answer – c) 66 m 11 cm
Q.11) Explanation – Measuring Length Worksheets for Grade 3
Write Metres (m) and Centimetres (cm) aligned in columns properly.
Subtract Metres (m) and Centimetres (cm) as we subtract numbers in Subtraction.
Hence, the difference is 23 m 11 cm
Correct Answer – c) 23 m 11 cm
Q.12) Explanation –Â
Step I:Write Metres (m) and Centimetres (cm) aligned in columns properly.
Step II:Subtract Metres (m) and Centimetres (cm) as we subtract numbers in Subtraction.
Hence, the difference is 39 m 14 cm
Correct Answer – a) 39 m 14 cm
Q.13) Explanation – Measuring Length Worksheets for Grade 3
Write Kilometres (km) and Metres (m) aligned in columns properly.
Add Kilometres (km) and Metres (m) as we add numbers in Addition.
Hence, the sum is 44 km 734 m
Correct Answer – a) 44 km 734 m
Q.14) Explanation –Â
Write Kilometres (km) and Metres (m) aligned in columns properly.
Add Kilometres (km) and Metres (m) as we add numbers in Addition.
Hence, the sum is 60 km 170 m
Correct Answer – c) 60 km 170 m
Q.15) Explanation – Measuring Length Worksheets for Grade 3
Write Kilometres (km) and Metres (m) aligned in columns properly.
Subtract Kilometres (km) and Metres (m) as we subtract numbers in Subtraction​.
Hence, the difference is 46 km 341 m
Correct Answer – c) 46 km 341 m
