When we share a box of apples and give the same number to Ann as to Bill, they will each get the same number.
When we share a box of apples and say "for every two that Ann gets, Bill gets one", Ann will get more than Bill.
Example
There are 24 apples in a box.
Ann and Bill share them out.
For every two that Ann gets, Bill gets one.
How many apples do they each get?
Answer
Every time Ann takes 2 apples, Bill takes 1 apple.
That's 3 apples taken.
They need to do this 24 ÷ 3 = 8 times.
So Ann takes 8 × 2 apples (the 8th multiple of 2).
Bill takes 8 × 1 apples (the 8th multiple of 1).
Ann takes 16 apples and Bill takes 8.
