Answer 2

32 : 40 = 48 : x

$\\ \frac{32}{40} = \frac{48}{x}$

cross multiplication

$32x = 40 \times 48 \\ \\ 32x = 4 \times 10 \times 48 \\ \\ x = \frac{4 \times 10 \times 48}{32} \\ \\ x = \frac{10 \times 48}{8} \\ \\ x = \frac{5 \times 2 \times 48 }{4 \times 2} \\ \\ x = \frac{5 \times 48}{4} \\ \\ x = \frac{5 \times 4 \times 12}{4} \\ \\ x = 5 \times 12 \\ \\ x = 60$

x = 60 is the answer
