Question

Are the following numbers in proportion?

$30,45,16,32$

Answer 1

Checking whether the numbers are in proportion or not :

The given numbers are $36,45,16,32$

We know that,

Four terms are said to be an in proportion if

Product of extreme$=$Product of means

Product of extremes $=$$36\times 32$

$=1152$

Product of means $=45\times 16$

$=720$

Since, $36\times 52\ne 45\times 16$

Hence, the given numbers are not in proportion
