Answer 1

Answer:

Step-by-step explanation:

$\frac{1}{10}$ + $\frac{1}{12}$ + $\frac{1}{15}$ = $\frac{6}{60}$ + $\frac{5}{60}$ + $\frac{4}{60}$ = $\frac{15}{60}$ = $\frac{1}{4}$

Contributions of A, B and C are

$\frac{1}{10}$ ÷ $\frac{1}{4}$ = $\frac{2}{5}$ = $\frac{6}{15}$

$\frac{1}{12}$ ÷ $\frac{1}{4}$ = $\frac{1}{3}$ = $\frac{5}{15}$

$\frac{1}{15}$ ÷ $\frac{1}{4}$ = $\frac{4}{15}$

A: 38400 × $\frac{6}{15}$ = 15,360

B: 38400 × $\frac{5}{15}$ =  12,800

C: 38400 × $\frac{4}{15}$ = 10,240
