Question

Por favor doy corona , es para hooooooyyyy

Answer 1

Explicación paso a paso:

4)

$\frac{m}{4} = \frac{n}{5} \\ m + n = 18 \\ . \\ \frac{m}{n} = \frac{4}{5} = k \\ m = 4k \\ n = 5k \\ . \\ 4k + 5k = 18 \\ 9k = 18 \\ k = 2 \\ . \\ m = 4(2) \\ m = 8 \\ n = 5(2) \\ n = 10$

5)

$\frac{m}{4} = \frac{n}{2} \\ m + n = 12 \\ . \\ \frac{m}{n} = \frac{4}{2} = k \\ \frac{m}{n} = 2 = k \\ m = 2k \\ n = k \\ . \\ 2k + k = 12 \\ 3k = 12 \\ k = 4 \\ . \\ m = 2(4) \\ m = 8 \\ n = 4$

6)

$\frac{m}{3} = \frac{n}{5} \\ m + n = 16 \\ . \\ \frac{m}{n} = \frac{3}{5} = k \\ m = 3k \\ n = 5k \\ . \\ 3k + 5k = 16 \\ 8k = 16 \\ k = 2 \\ . \\ m = 3(2) \\ m = 6 \\ n = 5(2) \\ n = 10$
