Is 13:15 and 30:26 a pair of equivalent ratios and why?

Given:

The two ratios are 13:15 and 30:26.

To find:

Whether the given ratios are equivalent or not.

Solution:

Two ratios are equivalent if the values of the ratio are equal after simplification.

And,

The first ratio is 13:15 and the value of second ratio after simplification is 15:13 both ratios are different, so,

Therefore, the required answer is "No", the given ratios are not a pair of equivalent ratios.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
