Answer:
He would need [tex]\frac{3}{2}=1\frac{1}{2}[/tex] cups of salt.
Step-by-step explanation:
We are given that,
The recipe requires [tex]\frac{3}{4}[/tex] cups of flour and [tex]1\frac{1}{8}=\frac{9}{8}[/tex] teaspoons of salr.
As Nick wants to make the recipe using 1 cup.
Let the amount of salt needed = x
The ratio of the flour and salt will be same.
So, we have,
[tex]\frac{\frac{3}{4}}{\frac{9}{8}}=\frac{1}{x}[/tex]
i.e. [tex]\frac{3\times 8}{4\time 9}=\frac{1}{x}[/tex]
i.e. [tex]\frac{2}{3}=\frac{1}{x}[/tex]
i.e. [tex]x=\frac{3}{2}=1\frac{1}{2}[/tex]
Thus, he would need [tex]\frac{3}{2}=1\frac{1}{2}[/tex] cups of salt if 1 cup of flour is used.
