[(25-11)+(15-9)] / 5

First you take care of the numbers in the brackets & then parenthesis.

25-11=14 and 15-9=6

Now you add both of those numbers together.

14+6=20

Now you divide.

20/5
=4

Do what's inside the parenthesis first then the brackets, then take that final result and divide by 25

[(25-11)+(16-9)]/25
[(14)+(7)]/25
21/25
= .84

Priya has a recipe for banana bread. She uses 7 ½ cups of flour to make 3 loaves of banana bread. Andre will follow the same rec

Mnenie [13.5K]

Answer:

Option B)

$b = \dfrac{2}{5}f$

Step-by-step explanation:

We are given the following in the question:

Priya uses $7\frac{1}{2}$ cups of flour to make 3 loaves of banana bread.

Thus, we can write the ration of bread to amount of flour used as:

$\text{Ratio} = \dfrac{3}{7\frac{1}{2}} = \dfrac{3}{\frac{15}{2}} = \dfrac{6}{15}$

Now, b loaves of banana bread using f cups of flour.

This measurement will follow the same ratio.

Thus, we can write:

$\dfrac{b}{f} = \dfrac{6}{15}\\\\b = \dfrac{2}{5}f$

Thus, the correct answer is

Option B)

$b = \dfrac{2}{5}f$
