Question

Fran is making pancakes. The recipe for the pancakes calls for \frac{1}{8} teaspoon of salt for every \frac{3}{4} cup of flour. Fran makes an amount of pancakes that needs 18 cups of flour. How much salt, in teaspoons, does Fran need to use for the pancakes?

Answer 1

3 teaspoons of salt

Explanation:

Fran is making pancakes. The recipe for the pancakes calls for
`(1)/(8)` teaspoon of salt for every
`(3)/(4)` cup of flour.

Amount of salt needed for
`(3)/(4)` cup of flour =
`(1)/(8)` teaspoon of salt

So,

Amount of salt needed for
`1` cup of flour =
`(1)/(8)((4)/(3))=(1)/(6)` teaspoon of salt

Now Fran makes an amount of pancakes that needs 18 cups of flour.

To find an amount of salt needed for
`18` cups of flour,

solve
`(1)/(6)(18)=3` teaspoons of salt
