Slushie
25% was thrown out because 10 is 1/4 of 40
Gwenuin
40 Spools are produced each day

10 are thrown away

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

[tex]= \frac{10}{40} \\ \\ = \frac{1}{4} \\ \\ = 0.25[/tex]

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

[tex]0.25 * 100 [/tex]

= 25%
