Question

Need to work out problem 7

Answer 1

Answer:

Explanations:

Ratio of A to B = 3/4

Ratio of B to C = 12/5

Multiply the ratio of A to B by 3/3

`\begin{gathered} \text{Ratio of A to B = }(3)/(4)*(3)/(3) \\ \text{Ratio of A to B = }(9)/(12) \end{gathered}`

Comparing the ratio of A to B and the ratio of B to C:

Ratio of A to B to C = 9 : 12 : 5

Total ratio = 9 + 12 + 5 = 26

Value of C = (5/26) x Total value

60 = (5/26) x Total value

Total value = (60 x 26)/5

Total value = 312

Value of A = (9/26) x Total value

Value of A = (9/26) x 312

Value of A = 9 x 12

Value of A = 108
