Answer:

Below in bold.

Explanation:

I won't do all these but you should get the idea of how to do them from the following. Be careful with the units if they are given . You must convert both values to the same unit before working out the percentages.

a. What proportion of 15 is 5:

As a fraction it is 5/15 = 1/3.

Now convert to a percentage by multiplying by 100:

1/3 * 100 = 33.33%

b. 20 and 10

= 10/20 = 1/2

1/2 * 100 = 50%.

e. £30 and £12

= 12/30

= 2/5

= 2/5 * 100 = 40%.

h. 6.4 is 0.4

= 0.4 / 6.4

= 4/64

= 1/16

= 1/16 * 100 = 6.25%

i. £144 is 12p

Here we convert the 2 values to pence:

£144 = 144 * 100 = 14,400p

The fraction is 12/14,400

= 1/1200

= 1/1200 * 100 = 0.083%

j. 1.2 m is 30 cm

Convert 1.2 m to cm

= 1.2 * 100 = 120

The fraction is 30/120 = 1/4

= 1/4 100 = 25%.
