Answer 1

Bom dia

$a) \frac{x}{10} = \frac{3}{15} \\ 15x = 10 \times 3 \\ 15x = 30 \\ x = 30 \div 15 \\ x = 2 \\ \\ b) \frac{x}{2} = \frac{9}{6} \\ 6x = 2 \times 9 \\ 6x = 18 \\ x = 18 \div 6 \\ x = 3 \\ \\ c) \frac{10}{x} = \frac{8}{4} \\ 8x = 10 \times 4 \\ 8x = 40 \\ x = 40 \div 8 \\ x = 5 \\ \\ d) \frac{3}{6} = \frac{x}{4} \\ 6x = 3 \times 4 \\ 6x = 12 \\ x = 12 \div 6 \\ x = 2$

bons estudos!
