nicks is making bread dough. the recipe requires 3/4 cu of flour and 1 1/8 teaspoons of salt. nick wants to make the recipe using 1 cup of flour,to maintain the ratio, how much salt is required when 1 cup of flour is used.

Respuesta :

3/4 cup flour      1 cup flour

----------------- =   --------------

1 1/8 tsp salt     x tsp salt

using cross products

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

change the mixed number

(1 1/8 to an improper fraction  = 9/8)

3/4 x =9/8

multiply each side by 4/3

3/4 x * 4/3 = 9/8 * 4/3

x =36/24

x =3/2

x= 1 1/2 tsp salt
