Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.

Answer:
eli= £180, freda = £260, geoff = £360
Step-by-step explanation:
eli : freda : geoff
9 : 13 : 18
9 + 13 + 18 = 40 parts
800 / 40 = 20
therefore 1 part = £20
20 x 9 = £180
20 x 13 = £260
20 x 18 = £360
Answer:
