Question

por favor ajudaaaaaa​

Answer 1

Resposta:

$\frac{y}{6}=\frac{1}{2}\quad :\quad y=3$

2y=6

y=6/2

y=3

$\frac{x}{4}=\frac{1}{2}\quad :\quad x=2$

2x=4

x=4/2

x=2

$\frac{4}{y}=\frac{2}{3}\quad :\quad y=6$

2y=4*3

y=12/2

y=6

$\frac{x}{15}=\frac{2}{3}\quad :\quad x=10$

3x=15*2

3x=30

x=30/3

x=10

Answer 2

Resposta:

$\frac{x}{4} = \frac{y}{6} = \frac{1}{2} \\ \\ \frac{x}{4} = \frac{1}{2} \\ \\ 2x = 4 \times 1 \\ \\ 2x = 4 \\ \\ x = \frac{4}{2} \\ \\ x =2 \\ \\ \frac{y}{6} = \frac{1}{2} \\ \\ 2y = 6 \\ \\ y = \frac{6}{2} \\ \\ y = 3$

$\frac{x}{15} = \frac{4}{y} = \frac{2}{3} \\ \\ \frac{x}{15} = \frac{2}{3} \\ \\ 3x = 30 \\ \\ x = \frac{30}{3} \\ \\ x = 10\\ \\ \frac{4}{y} = \frac{2}{3} \\ \\ 2y = 3 \times 4 \\ \\ 2y = 12 \\ \\ y = \frac{12}{2} \\ \\ y = 6$
