Question

Part A: Tyler used 1 1/4 gallons of paint to paint 5/7 of a fence. How many gallons will it take to paint the whole fence? Write a multiplication equation or a division equation to represent this question, then find the answer. Show your reasoning.

Answer 1

`(11)/(4)\text{ gallons is used to paint }(5)/(7)\text{ of the entire fence}`

if the whole fence is 1

then the number of gallons used is represented with x

`\begin{gathered} (11)/(4)\text{ --------- }(5)/(7) \\ \\ x\text{ ----------- 1} \end{gathered}`
`\begin{gathered} \text{cross multiplying} \\ x\text{ }*(5)/(7)=\text{ 1}*(11)/(4) \end{gathered}`
