Answer 1

Объяснение:

$1) \: \: \frac{x}{6} = \frac{8}{3} \\ x \times 3 = 6 \times 8 \\ 3x = 48 \\ x = \frac{48}{3} \\ x = 16$

$2) \: \: \frac{10}{y} = \frac{5}{4} \\ 10 \times 4 = y \times 5 \\ 40 = 5y \\ 5y = 40 \\ y = \frac{40}{5} \\y = 8$

$3) \: \: \frac{0.1}{9} = \frac{m}{10} \\ 0.1 \times 10 = 9 \times m \\ 1 = 9m \\ 9m = 1 \\ m = \frac{1}{9}$

$4) \: \: \frac{5}{x} = 1.3 \\ \frac{5}{x} = \frac{13}{10} \\ 5 \times 10 = x \times 13 \\ 50 = 13x \\ 13x = 50 \\ x = \frac{50}{13} \\ x = 3 \frac{11}{13}$

$5) \: \: \frac{6}{x} = 1 \frac{1}{7} \\ \frac{6}{x} = \frac{8}{7} \\ 6 \times 7 = 8 \times x \\ 42 = 8x \\ 8x = 42 \\ x = \frac{42}{8} \\ x = 5 \frac{2}{8}$

$6) \: \: 2 \frac{1}{2} = \frac{1.2}{x} \\ \frac{5}{2} = \frac{1.2}{x} \\ 5 \times x = 2 \times 1.2 \\ 5x = 2.4 \\ x = \frac{2.4}{5} \\ x = 0.48$
