Question

Kaitlin has ridden 26 miles of a bike course. The course is 65 miles long. What percentage of the course has Kaitlin ridden so far?0%Ś?X

Answer 1

From the given information, we can establish the following rule of three:

`\begin{gathered} 65\text{ miles ------ 100 \%} \\ 26\text{ miles ------- x} \end{gathered}`

where x denotes the unknown percentage. then, by cross-multiplying the above number, we have

`x*65\text{ miles=26miles}*100\text{ \%}`

Then, by dividing both sides by 65 miles, we get

`\begin{gathered} x=\frac{26\text{ miles }*\text{ 100 \%}}{65\text{ miles}} \\ x=40 \end{gathered}`

Therefore, the answer is 40 %
