a) £32 and £16

b) £12 and £36

Step-by-step explanation:

It is given that:

Amount to divide = £ 48

a) 2 : 1

Let,

x be the times of share.

2x + x = 48

3x = 48

Dividing both sides by 3

Thus,

2x = 2(16) = £32

x = £16

b) 1 : 3

x+3x=48

4x=48

Dividing both sides by 4

x = £12

3x = 3(12) = £36

Therefore,

a) £32 and £16

b) £12 and £36

b.an increase in a causes b to decrease
