Answer:
Sara has £75
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
105: 75
75 sweets.
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.
