Question

A machine produces 40 spools of nylon each day. On the first day of production, 10 spools have to be thrown away. What percentage is thrown out?

Answer 1

25% was thrown out because 10 is 1/4 of 40

Answer 2

40 Spools are produced each day

10 are thrown away

The fraction that represents how much has been thrown away is;


`= (10)/(40) \\ \\ = (1)/(4) \\ \\ = 0.25`

To get a percentage we multiply the decimal by 100, so;


`0.25 * 100`

= 25%
