Question

For each pair of numbers determine by what percent the second number is greater than the first, also determine by what percent the first number is less than the second. 10 and 15

Answer 1

The second number is 50% greater than the first number, and the first number is approximately 33.33% less than the second number.

Step-by-step explanation:

To determine the percent by which the second number is greater than the first, we can use the formula:

Percent increase = (difference/original) x 100%

In this case, the difference between 15 and 10 is 5.

So, the percent increase is:

(5/10) x 100% = 50%

To determine the percent by which the first number is less than the second, we can use the formula:

Percent decrease = (difference/original) x 100%

In this case, the difference between 15 and 10 is 5.

So, the percent decrease is:

(5/15) x 100% ≈ 33.33%
