How do you work 30 percent of 625?

Answer 1

Percent means "out of 100", so to find 30% of something you are actually multiplying the number by 30/100, which can also be expressed as 0.3

So, if you have a calculator, just type in 625 x 0.3 and you'll have your answer (187.5).

If you need to figure it out in your head, this method might be easier;

• Recognise that 30% is just 10% x 3
• Find 10% by moving the decimal place to the left (ie. 10% of 625.0 is 62.50)
• Figure out 62.5 + 62.5 (it equals 125 ... this is 20%)
• Add another 10% (62.5) to your total so far (125 + 62.5 = 187.5)
• There's your answer
