Question

Nick is making bread dough.

The recipe requires 3/4 cup of flour and 1 1/8 teaspoons of salt.

Nick wants to make the recipe using 1 cup of flour is used?

To maintain the ratio, how much salt is required when 1 cup of flour is used?

Answer 1

He would need
`(3)/(2)=1(1)/(2)` cups of salt.

Explanation:

We are given that,

The recipe requires
`(3)/(4)` cups of flour and
`1(1)/(8)=(9)/(8)` 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,

`((3)/(4))/((9)/(8))=(1)/(x)`

i.e.
`(3* 8)/(4\time 9)=(1)/(x)`

i.e.
`(2)/(3)=(1)/(x)`

i.e.
`x=(3)/(2)=1(1)/(2)`

Thus, he would need
`(3)/(2)=1(1)/(2)` cups of salt if 1 cup of flour is used.
