Answer:
3 teaspoons of salt
Step-by-step explanation:
Fran is making pancakes. The recipe for the pancakes calls for [tex]\frac{1}{8}[/tex] teaspoon of salt for every [tex]\frac{3}{4}[/tex] cup of flour.
Amount of salt needed for [tex]\frac{3}{4}[/tex] cup of flour = [tex]\frac{1}{8}[/tex] teaspoon of salt
So,
Amount of salt needed for [tex]1[/tex] cup of flour = [tex]\frac{1}{8}(\frac{4}{3})=\frac{1}{6}[/tex] teaspoon of salt
Now Fran makes an amount of pancakes that needs 18 cups of flour.
To find an amount of salt needed for [tex]18[/tex] cups of flour,
solve [tex]\frac{1}{6}(18)=3[/tex] teaspoons of salt
