Word Problems on Conversions of Units

Let us quickly revise conversion of units we learnt.

Now, we shall use the above conversions to solve some word problems.

Example 1

Since in the question the units of length are different, we convert it into one unit.

Conversion of length from meters to centimetres is as above,

Therefore, 2meters in centimetres is as above

40 meters in centimetres is as above

So a maximum of 18 shirts can be stitched from 40 m cloth

Now, Let's calculate how much cloth is required to make 18 shirts.

To find the remaining cloth we find difference between the total cloth given(4000 cm) and cloth used for making 18 shirts(3780 cm)

Therefore the cloth that is remaining is 130 centimetres.

Example 2

Since in the question the units of weight are different, we convert and make into one unit.

Converting kilograms to grams.

4 kilograms in grams is as above

800 kilograms in grams is as above

Weight of 1 medicine box is 4500 grams.
