to solve this question, we would have to equate the mathematical statements and then cross multiply

let the numbers of months she has read be represented by x


\begin{gathered} 60\text{books}=10\text{months} \\ 84\text{books}=x \end{gathered}

cross multiply both sides and solve for x


\begin{gathered} 60* x=84*10 \\ 60x=840 \end{gathered}

divide both sides by the coefficient of x


\begin{gathered} (60x)/(60)=(840)/(60) \\ x=14\text{ months} \end{gathered}

Hayley has read 84 books in 14 months
