Find the share of each of three classes , and if the school has to divide 588 LE between them according to the ratio , respectively, to buy decorations.
We can use the concept of "the sum of parts" to solve this problem.
The ratio of A : B : C is 2 : 4 : 6. So, the sum of parts = 2 + 4 + 6 = 12 equal parts.
Since 12 parts = LE, then one part = 588 12 = LE.
To find the share of each class, multiply the number of parts for that class by the value of one part.
