​

Answer 1

Boa Tarde

a)  $\frac{1}{2} = \frac{5}{x}$

1 * x = 5 * 2

x = 10

b)  $\frac{3}{4} = \frac{9}{x}$

3 * x = 9 * 4

3x = 36

x = $\frac{36}{3}$

x = 12

c)  $\frac{12}{7} = \frac{x}{14}$

12 * 14 = 7*x

7x = 168

x =  $\frac{168}{7}$

x = 24

d) $\frac{25}{3} = \frac{75}{x}$

25 * x = 75 * 3

25x * 225

x = $\frac{225}{25}$

x = 9
