# The ratio of the heights 1.50 m and 75 cm of two persons can be written as

(a) 1 : 50

(b) 1 : 5

(c) 2 : 1

(d) 1 : 2

**Solution:**

Given, the heights of two persons are 1.50 m and 75 cm.

We have to find the __ratio__ of the heights of two persons.

Let the height of first person be 1.50 m

We know 1 m = 100 cm

So, 1.50 m = 1.50 × 100

= 150 cm

The height of first person = 150 cm

Let the height of second person be 75 cm

Ratio = 150 : 75

= 30 : 15

= 2 : 1

Therefore, the required ratio is 2 : 1
