what is 70% of 250 and why is that the answer?
Understand what a percent means. It's just one hundredth of something.
So 70 per cent is 70 hundredths or 70/100 if you write it in math speak.
So 70 per cent of 250 is just 70/100 x 250. I'm sure you can do the last bit.
13 percent of 40 = 13/100 x 40
17 percent of 92 = 17/100 x 92 etc etc etc Not difficult.
Sometimes people get confused if they are asked a percentage of another percentage. Method is just the same. 5 percent of 18 percent is 5/100 x 18/100.
