How do you work out 2.25 percent of a number?

Answer 1

Work out 1% of the number by dividing it by 100;

then 2.25% of the number is 2.25 times this.

eg 2.25% of 80 is:

1% of 80 = 80 ÷ 100 = 0.8

→ 2.25% of 80 = 2.25 x (1% of 80)

= 2.25 x 0.8

= 1.8

This is the same as considering:

Percent means "out of 100"

→ 2.25 % = 2.25/100 (put the 2.25 over 100)

→ 2.25% of 80 = 2.25/100 x 80

= 1.8 (as before)
