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

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
