Question

a bakery uses 8 tablespoons of honey for every 10 cups of flour so how many tablespoons of honey do they use with 20 cups of flour

Answer 1

a bakery uses 8 tablespoons of honey for every 10 cups of flour so how many tablespoons of honey do they use with 20 cups of flour ​

we can use a rule of three

Step 1

define

`\begin{gathered} 8\text{ tablespoons of honey}\rightarrow10\text{ cups of flour} \\ x\text{ tablespoons of honey}\rightarrow20\text{ cups of flour} \end{gathered}`

there is a relation between the honey and the flour, is needs to be constant, so

Step 2

fin the ratio

`\begin{gathered} (8)/(10)=(x)/(20) \\ \end{gathered}`

Now

Step 3

solve for x

`\begin{gathered} (8)/(10)=(x)/(20) \\ x=(8\cdot20)/(10) \\ x=(160)/(10) \\ x=16 \end{gathered}`

so, he uses 16 tablespoons
