Question

If it takes ⅕ cup of flour to make ⅛ of a cake, how many cups of flour are needed to make a whole cake?

Answer 1

Answer:
`1(3)/(5)\text{ cups of flour are n}eeded\text{ to make a whole cake}`Explanations:

Number of cups of flour used to make 1/8 of a cake = 1/5

Number of cups of flour needed to make 1 cake = x

`\begin{gathered} x*(1)/(8)=(1)/(5) \\ (x)/(8)=\text{ }(1)/(5) \\ 5x\text{ =8} \\ x\text{ = }(8)/(5) \\ x\text{ = 1}(3)/(5) \end{gathered}`
`1(3)/(5)\text{ cups of flour are n}eeded\text{ to make a whole cake}`
