Answer 1

Resposta:

a) 450

b) 480

c) 72kg

Explicação passo-a-passo:

a)

$\frac{3000}{100} = \frac{x}{15}$

$100x = 45000$

$x = \frac{45000}{100}$

$x = 450$

b )

$\frac{1500}{100} = \frac{x}{32}$

$100x = 48000$

$x = \frac{48000}{100}$

$x = 480$

c)

$\frac{180}{100} = \frac{x}{40}$

$100x = 7200$

$x = \frac{7200}{100}$

$x = 72$
