In a family of 3 Children receive their allowances in the ratio of their ages which are 15years 12years and 9years If the total of the allowances is 30 how much does each child receive?

To find out how much each child receives, we first need to calculate the total parts in the ratio, which is 15 + 12 + 9 = 36 parts. Then, we divide the total allowance of 30 by the total parts (30 / 36 = 0.8333). Finally, we multiply this value by each child's age to find out how much each child receives: 15 x 0.8333 = 12.50, 12 x 0.8333 = 10.00, and 9 x 0.8333 = 7.50. Therefore, the children receive $12.50, $10.00, and $7.50 respectively.
