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?
Answer:
this one is rational and real :)
