Allison used 2.5 half cups of flour to make a cake, and 3 over 4of a cup of flour to make a pie. if she started with 4 cups of flour, how many cups of flour does she have left?

Allison has 3/4 cups of flour left.

Step-by-step explanation:

Allison used flour twice, the first time she used 2.5 cups of flour, and the second time she used 3/4 cups of flour. Let's convert these two the the same unit.

2.5= 2 1/2 or 5/2

Let's make this have the same base so it will be easier to add 3/4 to it.

5/2=10/4

We know she used both of these amounts of flour so let's add them. 10/4+3/4=13/4

We know she used 13/4 cups of flour. Let's convert 4 cups of flour to have the denominator of 4.

4=16/4

Now, we just have to subtract how much flour she used to make the pie and cake.

16/4-13/4=3/4

Allison has 3/4 cups of flour left.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
