Answer 1

Explicación paso a paso:

1)

$\frac{5}{4} = \frac{c}{28} \\ 140 = 4c \\ \frac{140}{4} = c \\ 35 = c$

2)

$\frac{3}{4} = \frac{x}{8} \\ 24 = 4x \\ \frac{24}{4} = x \\ 6 = x$

3)

$\frac{2}{n} = \frac{8}{32} \\ 64 = 8n \\ \frac{64}{8} = n \\ 8 = n$

4)

$\frac{15}{70} = \frac{30}{x} \\ 15x = 2100 \\ x = \frac{2100}{15} \\ x = 140$

5)

$\frac{x}{8} = \frac{9}{12} \\ 12x = 72 \\ x = \frac{72}{12} \\ x = 6$

6)

$\frac{7}{8} = \frac{56}{p} \\ 7p = 448 \\ p = \frac{448}{7} \\ p = 64$

7)

$\frac{3}{7} = \frac{z}{28} \\ 84 = 7z \\ \frac{84}{7} = z \\ 12 = z$

8)

$\frac{y}{5} = \frac{8}{20} \\ 20y = 40 \\ y = \frac{40}{20} \\ y = 2$

9)

$\frac{4}{5} = \frac{12}{m} \\ 4m = 60 \\ m = \frac{60}{4} \\ m = 15$

10)

$\frac{20}{x} = \frac{6}{15} \\ 300 = 6x \\ \frac{300}{6} = x \\ 50 = x$
