Question

Find the ratio of 90 cm to 1.5 m.

Answer 1

The two quantities are not in the same units. Therefore, we have to convert them into the same units.

1.5 m = 1.5 × 100 cm = 150 cm.

Therefore, the required ratio is 90: 150.

= `90/150 = (90 xx 30)/(150 xx 30) = 3/5`.

Required ratio is 3: 5.
