Question

me ayudan ? porfavor ​

Answer 1

$\frac{3}{3} = \frac{9}{x} \\ 1 = \frac{9}{x} \\ x = 9$

$\frac{1}{3} = \frac{9}{n} \\ n = 9 \times 3 \\ n = 27$

$\frac{0}{5} = \frac{x}{25} \\ 0 = \frac{x}{5} \\ x = 0$

$\frac{x}{3} = \frac{8}{12} \\ x = \frac{8}{4} \\ x = 2$

$\frac{ - 5}{7} = \frac{35}{q} \\ q \times \frac{ - 5}{7} = 35 \\ q = 35 \times \frac{7}{ - 5} = 7 \times \frac{7}{ - 1} = - 49$

$\frac{5}{x} = \frac{20}{40} \\ \frac{1}{x} = \frac{4}{40} \\ x = \frac{40}{4} = 10$
