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)
