Answer:
7.5
Step-by-step explanation:
Let R = rice.
Let W = wheat.
Let C = corn.
Let X = special cereal mixture
Given the following data;
Ratio of rice, wheat and corn = 2:3:5
Total quantity of rice = 3 pounds.
Ratio = 2 + 3 + 5 = 10
For rice;
2/10 * X = 3
Cross multiplying, we have;
2X = 30
X = 30/2 = 15
Therefore, the total quantity of the special cereal mixture is 15 pounds.
To find the total amount of corn;
C = 5/10 * 15
C = 75/10
C = 7.5 pounds.
Hence, the special cereal mixture contains 7.5 pounds of corn.
To find the total amount of wheat;
W = 3/10 * 15
W = 45/10
W = 4.5 pounds.
Check;
Special cereal mixture = rice + wheat + corn.
Special cereal mixture = 3 + 4.5 + 7.5
Special cereal mixture = 15 pounds.
