Question

State true or false:

$6:3$ and $5:15$ are in proportion.

• A. True
• B. False

Answer 1

The correct option is B False

To check $6:3$ and $5:15$ are in proportion

We need to equate the two ratios and check whether it is true.

Given, $\frac{6}{3}=\frac{5}{15}$

$⟹\frac{6}{3}=\frac{1}{3}$

$⟹6=1$, which is not true.

Hence, $6:3$ and $5:15$ are not in proportion.
