Step-by-step explanation:

Let x be the pound.

The ratio is 5:7

Then,

The 1st pound be 5x

and

2nd pound be 7x

Then,

5x + 7x = £1200

12x = £1200

x = £1200/12

x = £100

Then,

The 1st pound be

5x = 5×£100 = £500

And

2nd pound be

7x = 7×£100 = £700

ANSWER= 500:700


HINT: ADT (add, divide, times)

Add (the ratio) — 5+7 = 12
Divide (by the amount) — £1200/100 = 100
Times (by the ratio) — 5 x 100 = £500
7 x 100 = £700

500 : 700

( and of course you can always double check your answer by adding £500 to £700 and it should give you the original price £1200)
