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.

    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
