Question

Q2. Express the first quantity as a percentage of the second quantity.

(a) 2 years, 18 months (b) 225mm, 20cm

Answer 1

a. 133.33%

b. 112.5%.

Explanation:

(a) 2 years = 24 months.

So the fraction is 24/18 = 4/3.

As a percentage it is

4/3 * 100 = 133.33%.

b) 20 cm = 200 mm

so the answer is

(225/200) * 100

-= 1.125 * 100

= 112.5 %.
