Question

Find the ratio of the second quantity with the first in its simplest form.
(i) 52 cm, 117 cm
(ii) 8 yr. 4 months, 11 yr. 8 month
(iii) 1.44m, 2.40m

Answer 1

(i) Ratio of 117 cm to 52 cm = $\frac{117}{52}=\frac{9}{4}$ = 9:4

(ii) 8 years 4 months = 96 months + 4 months = 100 months
11 years 8 months = 132 months + 8 months = 140 months
Ratio of 140 months to 100 months = $\frac{140}{100}=\frac{7}{5}$ = 7:5

(iii) Ratio of 2.40 m to 1.44 m = $\frac{2.40}{1.44}=\frac{5}{3}$ = 5:3
