Question

Jimmy is working at a factory where they make cars and trucks in the ratio five to four if the factory makes 100 trucks how many cars will it produce

Answer 1

From the basic knowledge of ratio:

cars : trucks

`\begin{gathered} (5)/(4)\text{ = }(x)/(100) \\ \text{cross}-\text{ multiply,} \\ 4\text{ }*\text{ x = 5 x 100} \\ 4x\text{ = 500} \\ \text{Divide both sides, we have:} \\ x\text{ =500/4} \\ x\text{ = 125} \end{gathered}`
