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?
40 Spools are produced each day
10 are thrown away
The fraction that represents how much has been thrown away is;
\(= \frac{10}{40} \\ \\ = \frac{1}{4} \\ \\ = 0.25\)
To get a percentage we multiply the decimal by 100, so;
\(0.25 * 100\)
= 25%
