Question

Divide 57 into two parts such that one part is equal to 2 thirds of the other

Answer 1

Answer:

34.2 & 22.8

Step-by-step explanation:

• let one part be x
• other part be 2/3 x

$x + \frac{2}{3} x = 57 \\ \frac{3x + 2x}{3} = 57 \\ 5x = 57 \times 3 \\ 5x = 171 \\ x = \frac{171}{5} \\ x = 34.2$

• other number = 2/3 × 34.2 = 22.8
