we can make a relation
[tex]\begin{gathered} \frac{2}{3}\longrightarrow4 \\ \\ x\longrightarrow1 \end{gathered}[/tex]where x is the missing value
if she bikes 2/3km in 4 minutes how much kilometers she bike on 1 minute?
we solv using cross multiplication
we multiply 1 and 2/3 and the divide by 4
[tex]\begin{gathered} x=\frac{1\times\frac{2}{3}}{4} \\ \\ x=\frac{\frac{2}{3}}{4} \\ \\ x=\frac{1}{6} \end{gathered}[/tex]she will bike 1/6km in one minute
