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

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
