Question

Check whether the following is in continued proportion or not.$4,6\mathrm{and}9.$

Answer 1

Check the numbers are in continued proportion or not

In continued proportion, the ratio of first to the second and second to the third are equal.

Let, $4:6::6:9$

$\Rightarrow \frac{4}{6}=\frac{6}{9}$

$\Rightarrow \frac{2}{3}=\frac{2}{3}$

Hence,$4,6\mathrm{and}9$ are in continued proportion.
