Question

what is the difference of the totals of the runners who ran 1/2 if a mile and who ran 1/3 of a mile answer

Answer 1

To find the difference between the rates of the runners, we have to do

subtraction

$\because d=\frac{1}{2}-\frac{1}{3}$

To do the subtraction we must make the denominators the same

∵ The lowest common multiple of 2 and 3 is 6

$\begin{gathered} \therefore d=\frac{1\times3}{2\times3}-\frac{1\times2}{3\times2} \\ \therefore d=\frac{3}{6}-\frac{2}{6} \end{gathered}$

Now we can subtract their numerators

$\begin{gathered} \because d=\frac{3}{6}-\frac{2}{6} \\ \therefore d=\frac{1}{6} \end{gathered}$

The difference is 1/6
