Terri buys five and seven eighths ounces of chocolate chips. She uses four and four sixths ounces in a recipe. How many ounces of chocolate chips does she have left? a one and ten forty eighths ounces
b one and three fourteenths ounces
c two and ten forty eighths ounces
d two and three fourteenths ounces

(A)

Step-by-step explanation:

To find how many chocolate chips are left, you have to subtract the amount used for the recipe from the original amount which is:

To subtract the two mixed numbers, first you have to convert them to improper fractions which would make the expression:

Then, in order to subtract the two improper fractions, since they have different denominators, you have to make them have the same denominator. The LCM (Least Common Multiple) of 8 and 6 is 24, so to subtract the two fractions, you need both of them to have a denominator of 24. That would make the expression:

To subtract these two fractions, since they have the same denominators, you can subtract the numerators and keep the denominators. That would make the

which is, as a mixed number, , which is .

Hope this helps :)

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
