Question 2

To convert a percentage into a decimal, divide by 100:

⇒ 4% = 4 ÷ 100 = 0.04

⇒ 25% = 25 ÷ 100 = 0.25

If a is 4% of b then: a = 0.04b

If b is 25% of c then: b = 0.25c

Substitute the second equation into the first:

⇒ a = 0.04b

⇒ a = 0.04(0.25c)

⇒ a = 0.01c

As 0.01 = 0.01 Ă— 100 = 1%

Therefore, a is 1% of c.

⇒ a = 0.01c

⇒ a ÷ 0.01 = c

⇒ 100a = c

As 100 = 100 Ă— 100 = 10,000%

Therefore, c is 10,000% of a.
