Answer:
7:5:8
Explanation:
We write as much of the ratio as we can.
apple : orange : cranberry
1/4 : 2/5 : x
Now we can find x.
Fraction of cranberry juice:
1 - (1/4 + 2/5) = 20/20 - (5/20 + 8/20) = 20/20 - 13/20 = 7/20
We write the complete ratio.
apple : orange : cranberry
1/4 : 2/5 : 7/20
Since 20 is the common denominator, we multiply all fractions by 20.
apple : orange : cranberry
1/4×20 : 2/5 × 20 : 7/20 × 20
Do the 3 multiplications.
apple : orange : cranberry
5 : 8 : 7
Now write the ratio in the order the problem asks.
cranberry : apple : orange
7 : 5 : 8
Answer: 7:5:8
