Question

Help and please explain

Answer 1

alright so you need to find the unit rate for both of these bought items.

5.25(5 1/4) pounds is equal to $2.10 if you set it into an equation

5.25x = $2.10

x represents how much is the price for one pound of banana

to find x you divide $2.10 by 5.25

you can either plug that into a calculator (.4 is the answer)

to divide a fraction

2.10 / 1 ÷ 21/4

switch the 21/4

2.10/1 ÷ 4/21

instead of using division to solve this you actually multiply!(don't ask me why)

2.10 × 4 = 8.4

21 × 1 = 21

now divide 8.4 by 21 = $0.4 for each pound of bananas

do the same on the other persons payment

3.25x = 6.5

x = 0.5

now you answer it. which one is cheaper?
