Pip and Sara win some money and share it in the ratio 7:5. Pip gets £30 more than Sara. How much did Sara get?

75 sweets.

Step-by-step explanation:

Pip gets 7 / (7+5) = 7/12.

Let Sara get x sweets so Pip gets 7/5 x sweets.

7/5 x = x + 30

2/5 x = 30

x = 5/2 * 30 = 75.

Sara gets 75 sweets.

Sara has £75

Step-by-step explanation:

Pip : Sara

7 : 5

If Pip gets £30 more than Sara, then

5x+30=7x

Where x is £?

Subtract 5x from both sides

30=2x

Divide both sides by 2

x=£15

£15

Pip : Sara

105: 75
