Find the amount of juice that a pear and a orange can gives...
Can you now finish the problem ..........
Find total mixture
can you finish the problem........
3 pear gives 8 ounces of juice .
A pear gives \(\frac {8}{3}\) ounces of juice per pear
2 orange gives 8 ounces of juice per orange
An orange gives \(\frac {8}{2}\)=4 ounces of juice per orange.
Therefore the total mixer =\({\frac{8}{3}+4}\)
If She makes a pear-orange juice blend from an equal number of pears and oranges then percent of the blend is pear juice= \(\frac{\frac{8}{3}}{\frac{8}{3}+4} \times 100 =40\)
