Understanding Percentages:

A percentage is a fraction expressed as a number out of 100. The symbol "%" represents "per cent" or "out of 100". For instance, 50% means 50 out of 100, or 50/100, which simplifies to 1/2.

(21 / 50) * 100% = 42%

Therefore, 21 is 42% of 50.

Step-by-Step Breakdown:

1. Divide the part by the whole: 21 ÷ 50 = 0.42
