Answer 1

1 1/2 teaspoon of salt is required

Explanation:

The recipe requires 3/4 cup of flour and Nick wants to make the recipe using 1 cup of flour.

The recipe requires 1 1/8 teaspoon of salt and Nick wants to know how much salt he heeds.

Consider short description:

3/4 cup of flour - 1 cup of flour,

1 1/8 teaspoon of salt - x teaspoon of salt.

Mathematically, you can wrte a proportion:

3/4 = 1 / x

1 1/8

Then

3/4 * x = 1 x 1 1/8,

3x/4 = 9/8,

3x x 8 = 4 x 9,

24x = 36,

x = 36/24 = 3/2 = 1 1/2
