Question

Students are voting for a new school mascot so far the results show 3/10 of the students voted for fightin titans 1/2 of the students voted for nifty knight and the rest of the students have not voted yet.What fraction of the student population has not yet voted

Answer 1

`(1)/(5)` didn't vote

Explanation:

3/10 voted for fighting tians

1/2 voted for nifty knights

In total, what fraction voted?? We take common denominator and sum the two fractions. Shown below:

`(3)/(10)+(1)/(2)\\=(3)/(10)+(5)/(10)\\=(8)/(10)`

The rest DIDN'T VOTE. To find the fraction that didn't vote, we need to subtract 8/10 from 1 (whole). Shown below:

`1-(8)/(10)\\=(10)/(10)-(8)/(10)\\(2)/(10)\\=(1)/(5)`
