Given:
Riya's height = 150 cm
Her brother's height = 160 cm
Riya's weight = 45 kg
Her brother's weight = 48 kg
To find:
Are their heights in proportion to their weight?
Solution:
The ratio of Riya and her brother's height will be:
= 150: 160
On simplifying the ratio, we get:
= 15:16
The ratio of Riya and her brother's weight will be:
= 45:48
On simplifying the ratio, we get:
= 15:16
Since the basic ratios of their height and weight are equal hence we can say that their heights are in proportion to their weight.
