Question

complete the ratio table.
1 5
□ 35
20 50
22 55
24 60

Explanation:

Step1: Find the ratio of known pairs

First, take the pair (20, 50). The ratio of the first number to the second number is $\frac{20}{50}=\frac{2}{5}$. Let's check another pair, (22, 55): $\frac{22}{55}=\frac{2}{5}$. And (24, 60): $\frac{24}{60}=\frac{2}{5}$. So the ratio of the first column to the second column is $\frac{2}{5}$.

Step2: Find the missing value

Let the missing value be $x$. We know that $\frac{x}{35}=\frac{2}{5}$. Cross - multiplying gives $5x = 35\times2$. Then $5x=70$, and dividing both sides by 5, we get $x = 14$.

Answer:

14
