Question

Joe has eaten 3/5 of a pizza, Jane has eaten 1/7 of a pizza.

How many times more pizza has Joe eaten more than Jane?

Compared to Jenny, Sally is 7/8 as tall and May is 6/7 as tall.
How much taller is Sally than May?

So confused, they may be really simple but i've read it too many times and it dosn't make sense anymore haha.

Answer 1

3/5÷1/7 use the recipical

3/5 ÷ 7/1= 21/5

21÷5=4 1/5 I think is your first answer but I could be wrong

7/8 6/7

you must find common denominator.

49/56 - 48/56= 1/56 again I could be wrong

Answer 2

1.
3/5 - 1/7

21/35 - 5/35

16/35

Joe ate 16/35 more pizza than Jane.

2.
7/8 - 6/7

49/56 - 48/56

1/56

Sally is 1/56 taller than May.
