Question

Find the amount of increase if 580 is increased by 10%.

Answer 1

The 10% of the number 580 is obtained by multiplying by 10 and dividing by 100:

`580\cdot(10)/(100)=(580\cdot10)/(100)=(5800)/(100)=58.`

If we increase the number 580 by a 10% percent, we are increasing the number by 58. So the amount of increase is 58.

Answer: 58
