Write and solve an equation of ratios to answer this.
2.25 cup        x
-------------- = -------------
0.375 cup      1 cup
                                         2.25
cross-multiplying, 2.25 = 0.375x. Â Solving for x, x = ---------- = 6
                                          0.375
Brianna would need to use 6 cups of flour if she wants the mixture to contain 1 cup of baking soda.

Answer:
6 cups is the answer.
Step-by-step explanation:
The recipe for chocolate chip cookie calls for 2 1/4 cups(9/4) of flour and 3/8 cup of baking soda.
Number of cups of flour Brianna will need to use is given by:
[tex]\frac{2\frac{1}{4}}{\frac{3}{8} }[/tex]
Solving this we get;
=> [tex]\frac{\frac{9}{4}}{\frac{3}{8} }[/tex]
=> [tex]\frac{9}{4}\times \frac{8}{3}[/tex]
= 6
Hence, the answer is 6 cups.
