Question

Check whether $2,3,8,12$ are proportional or not:

Answer 1

Explanation:

Four quantities are said to be in proportion when,

$\text{Product of extremes terms = Product of means terms}$,

The first and last terms are called extremes terms, while the second and third terms are called middle or means terms.

Product of extremes terms $=2\times 12=24$

Product of means terms $=3\times 8=24$

Therefore, $\text{Product of extremes terms = Product of means terms}$

Hence, $2,3,8,12$ are proportional.
