Question

(b) Angles a and c are
6 $44 is shared between David, Jo and Mary in the ratio 2:3:5
How much does each receive?

Answer 1

                  David receives $ 8,8

                  Jo receives $ 13,2

                  Mary receives $ 22

Step by step explanation:

The sum S of 2, 3, and 5 is S = 2 + 3 + 5 = 10.

The following proportions are proposed:

1) 44/10 = X / 2, where X is what corresponds to David.

   The product of the means must be equal to that of the extremes. Then:

  10. X = 44 . 2

         X = (44 . 2) / 10

         X = 8, 8

2) 44/10 = Y / 3, where Y is what corresponds to Jo. Then:

   10. Y = 3 . 44

          Y = (3 . 44) / 10

          Y = 13,2

3) Let Z correspond to Mary. Therefore:

  Z = 44 - 8,8 - 13,2

  Z = 22

David receives $ 8,8

Jo receives $ 13,2

Mary receives $ 22
