Question

Nick is making bread dough. The recipe requires 3/4 cup of flour and 1 1/8 teaspoon 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?
(explain)

Answer 1

Answer:

x = 1 $\frac{1}{2}$

Step-by-step explanation:

make equal equations first

$\frac{3/4}{1 and 1/8}$  =  $\frac{1}{x}$

cross multiply to get: 3/4x = 1 $\frac{1}{8}$  

divide by 3/4 on both sides: x = 1 $\frac{1}{2}$

Answer 2

1 1/2 tsp of salt is required


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 divided by 1 1/8
then 3/4 times x = 1 time 1 1/8
3x/4 =9/8
24x = 36
X = 36/24 = 3/2 = 1 1/2
