alguém me ajuda? preciso disso urgente

Answer 1

$a) \frac{x}{3} = \frac{10}{6} \\ 6x = 30 \\ x = \frac{30}{6} \\ x = 5$
$b) \frac{x}{4} = \frac{91}{52} \\ 52x = 364 \\ x = \frac{364}{52} \\ x = 7$
$c) \frac{x}{7} = \frac{18}{21} \\ 21x = 126 \\ x = \frac{126}{21} \\ x = 6$
$d) \frac{x}{105} = \frac{2}{30} \\ 30x = 210 \\ x = \frac{210}{30} \\ x = 7$
$e) \frac{x}{8} = \frac{36}{32} \\ 32x = 288 \\ x = \frac{288}{32} \\ x = 9$
$e) \frac{x}{3} = \frac{128}{48} \\ 48x = 384 \\ x = \frac{384}{48} \\ x = 8$
