(b)225 mm, 20cm

Answer 1

Step-by-step explanation:

Given Express the first quantity as a percentage of the second quantity. (a)2 years, 18 months (b)225 mm, 20 cm  

• We need to express the first quantity as a percentage of second quantity.
• So given 2 years, 18 months
• We need to convert years to months so that both have same units.
• So 2 years = 24 months
• Now we have 24 months, 18 months
• So percentage will be 24 / 18 x 100 = 133.33%
• Similarly for the second one we have 225 mm , 20 cm
• Now 10 mm = 1 cm
• So 225 mm will be 225 / 10 = 22.5 cm
• So we have 22.5 cm, 20 cm
• So percentage will be 22.5 / 20 x 100 = 112.5%
