Your answer is A.

And yes, very confusing problem. The whole amount is all of the shaded area under the number line, which is 2 1/3. So that narrows our answer choices down to A and B.

We know it’s being divided by 2/3 because of the bracketed sections below the shaded area. This is confirmed by the fact that in A and B, 2 1/3 is divided by 2/3.

So the question is then how many groups of 2/3 do we have. We have 3 full groups, or brackets of 2/3. The fourth bracket only has one of the two sections filled, which means that is a half measure of a 2/3. Putting this in words is really hard, LOL.

But we have 3 full brackets each measuring 2/3, and 1/2 of a bracket measuring 2/3, so the answer is 3 1/2.

I feel like this took me a good bit of time to get my brain around this morning. Have a good day.

1st transformation:
A'=(-3,-4)\\
B'=(-7,-4)\\
C'=(-3,-8)\\

2nd transformation:
When you rotate a point around the origin by 180 degrees, you change both coordinates to opposite values.
A''=(3,4)\\ B''=(7,4)\\ C''=(3,8)\\ D''=(7,8)

1/3 cup of flour is used to make 5 dinner rolls.
RoseWind [281]

we know that

\frac{1}{3} cup of flour is used to make 5 dinner rolls.

Part a) How much flour is needed to make one dinner roll?

by using proportion

\frac{\frac{1}{3}}{5}  =\frac{x}{1} \\ \\ x=\frac{\frac{1}{3}}{5}\\ \\ x=\frac{1}{15}

therefore

the answer Part a) is

To make one dinner roll is needed \frac{1}{15} cup of flour

Part b) How many cups of flour are needed to make 3 dozen dinner rolls?

Multiply the value obtained in part a) by 36

so

\frac{1}{15} *36=\frac{36}{15} \\ \\ =\frac{12}{5}

\frac{12}{5} =2\frac{2}{5}

therefore

the answer Part b) is

To make 3 dozen dinner rolls are needed 2\frac{2}{5} cup of flour

Part c) How many rolls can you make with 5 2/3 cups of flour?

5\frac{2}{3} =\frac{17}{3}

by using proportion

\frac{\frac{1}{3}}{5}  =\frac{\frac{17}{3}}{x} \\ \\ \frac{x}{3} =\frac{85}{3} \\ \\ x=85

therefore

the answer part c) is

85 rolls
