Step-by-step workings
Why this works
To find 30% of 1500, we first convert the percentage to a decimal. 30% means 30 out of every 100, so we divide 30 by 100 to get 0.3. We then multiply this decimal by 1500 to find our answer of 450.
This works because a percentage is simply a fraction of 100. 30% is the same as the fraction 3/10 (three tenths). Multiplying any number by 0.3 gives you exactly 30 parts out of every 100 of that number.
Result = (30 ÷ 100) × 1500
Result = 0.3 × 1500 = 450

To verify that 450 is 30% of 1500, divide the answer by 1500 and multiply by 100:
(450 ÷ 1500) × 100 = 30%
