Ava has a dozen apples of the same size and a dozen watermelons of the same size. Ava uses her juicer to extract 14 ounces of watermelon juice from 2 watermelons and 1 ounces of apple juice from 7 apples. She makes a watermelon-apple juice blend from an equal number of watermelons and apples. What percent of the blend is watermelon juice?​

Answer 1

14 ounces watermelon juice.....................2 watermelons

x.......................................................................1 watermelon

x = 14:2 = 7 ounces of watermelon juice

1-ounce apple juice.........................7 apples

y...........................................................1 apple

y = $\frac{1}{7}$ ounces of apple juice

$\frac{1}{7} + 7$ = $\frac{50}{7}$ ounces of blend juice contains......................7 ounces of watermelon juice

100 ounces ..................................................................z

z = $\frac{100*7}{\frac{50}{7} }$ = $\frac{100*7*7}{50}$ = 98 % of blend juice is watermelon juice
