Question

the ratio of isabella's money to Shane's money is 5:10.if Isabelle has $55 how much money do Shane have?what about they have together?

Answer 1

`\begin{gathered} \text{ratio 5:10} \\ \text{isabelle has 55 then} \\ (55)/(5)=11 \end{gathered}`
`\begin{gathered} In\text{ order to conserve the ratio, it must ocurr that} \\ \text{Shane has 10}\cdot11=110 \\ \text{why? because} \\ (110)/(10)=(55)/(5)=11 \end{gathered}`
`\text{Together Isabelle and Shane have 110+55=165}`
