Answer :
Answer:
Explanation:
The fact that Kalen earned a 75% means that 6 questions are 75% of the total number of questions. And for a moment, if we call T the total number of questions, then we know that
[tex]T\times\frac{75\%}{100\%}=6[/tex]which simplifies to
[tex]T\times0.75=6[/tex]Dividing both sides by 0.75 gives
[tex]T\times0.75\div0.75=6\div0.75[/tex][tex]T=6\div0.75[/tex][tex]T=8[/tex]Hence, the total number of questions on the test was 8.
In short, the formula for solving such problems is
[tex]T=\frac{100}{\text{percent}}\times n\text{umber}[/tex]where number is that which is some percent of the original amount.
