Question

WILL GIVE BRAINLIEST

Answer 1

Answer:

Part 1) option B $\frac{15}{42}$

Part 2) option B $\frac{8}{20}$

Part 3) option C $2:1$

Step-by-step explanation:

Part 1)

we know that

By proportion

$\frac{5}{14}=\frac{x}{42}\\ \\14x=5*42\\ \\ x= 5*42/14\\ \\x=15$

so

the ratio is equal to

$\frac{15}{42}$

Part 2)

we know that

By proportion

$\frac{2}{5}=\frac{x}{20}\\ \\5x=2*20\\ \\ x= 40/5\\ \\x=8$

so

the ratio is equal to

$\frac{8}{20}$

Part 3) we know that

The ratio $10:5$ is equal to $\frac{10}{5}=\frac{2}{1}$

and

$\frac{2}{1}$ is equal to $2:1$

therefore

the answer is the option C

Answer 2

1. B(15 to 42)
2. B(8 to 20)
3. C(2:1)
