Question

What is 80% of 685?

Answer 1

To know the percentage of a quantity, we have to divide the percentage we want to know (in this case 80%), over 100%. Then, that part has to be multiplied by that result as it is the part that corresponds to 80%.

0. Dividing 80% over 100%

`(80)/(100)=0.8`

2. Multiplying by the quantity

`0.8*685=548`

Answer: 548
