Answer:
Part 1) 40% of the 80 ounce bottle of apple juice is water
Part 2) 75% of the 64 ounce bottle of orange juice is water
Part 3) An 64 ounce bottle of orange juice has a greater percent of water
Step-by-step explanation:
Part 1) we know that
An 80 ounce bottle of apple juice contains 32 ounces of water
In this problem
80 ounce bottle of apple juice represent the 100%
so
using proportion
Find out how much percentage represent 32 ounces of water
Let
x ----> the percentage of ounces of water
![(80)/(100)=(32)/(x) \\\\x=100(32)/80\\\\x=40\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tzz626e2dmeblmijex2yi1exztf87tv45j.png)
therefore
40% of the 80 ounce bottle of apple juice is water
Part 2) we know that
An 64 ounce bottle of orange juice contains 48 ounces of water
In this problem
64 ounce bottle of orange juice represent the 100%
so
using proportion
Find out how much percentage represent 48 ounces of water
Let
x ----> the percentage of ounces of water
![(64)/(100)=(48)/(x) \\\\x=100(48)/64\\\\x=75\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/psbv44dukuins5043g8sptjo8gmrge90n5.png)
therefore
75% of the 64 ounce bottle of orange juice is water
Part 3) which juice has a greater percent of water?
Compare the percentage of ounces of water in both bottles
![75\% > 40\%](https://img.qammunity.org/2020/formulas/mathematics/middle-school/idmakao8oh72oainbt701k2s6pyrsro6hw.png)
therefore
An 64 ounce bottle of orange juice has a greater percent of water
