Question

Check whether $1.7,4,5.1,35$ 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 $=1.7\times 35=59.5$

Product of means terms $=4\times 5.1=20.4$

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

Hence, $1.7,4,5.1,35$ are not proportional.
