Hi!

If the number can be represented as a ratio (fraction or repeating decimal), it is rational. An irrational number, like pi, does not repeat, but goes on forever.

Hope this helps!

A store salesperson is paid 3% of his sales as a commission. He made sales of $2500. How much was his commission?

PolarNik [594]

1) Write 3% as 3/100

2) Since, finding the fraction of a number is same as multiplying the fraction with the number, we have:

$\frac{3}{100}$ of 2500 = $\frac{3}{100}$ × 2500

Therefore, the answer is 75

If you are using a calculator, simply enter 3÷100×2500 which will give you 75 as the answer.

Commission = $75
