Question

Two ratios are said to be in ________ if they are equivalent.

• A. unitary
• B. proportion
• C. congruence
• D. similarity

Answer 1

The correct option is B proportion

Two ratios are said to be in proportion if they are equivalent.

Ex: Consider $2:3$ and $4:6$ .
$4:6=\frac{4}{6}=\frac{2\times 2}{2\times 3}=\frac{2}{3}$
Therefore, 2 : 3 and 4 : 6 are equivalent ratios. So, they can be written as
2 : 3 :: 4 : 6 .
