Step-by-step explanation:
Given:
To get a B in math, Alexandria Pappas must<u> average 80</u> on five tests.
Scores on the first four tests were <em>82, 74, 82, and 74.</em>
Question asked:
What is the lowest score that she can get on the last test and still get a B?
Solution:
Let lowest score she can get on the last test = 
As we know:

Thus, she can get 88 score on the last test to get a B in math.
numerator = top part of the fraction
denominator = bottom part of the fraction
* means multiply
a.
you can only add the numerator when the denominator is the same
cant add the denominator
denominator has to be the same
1/5 = 4/20
4/20 + 7/20 = 11/20
b.
1 7/8 = 15/8
3/4 ÷ 15/8 =
3/4 * 8/15 =
24/60 = divide both top and bottom by 12 =
2/5
12 times 2 is 24, and 24 times 2 is 48, so there was 48 cookies
IF the original number was an integer, then the digit in the ones place of the final product is a zero ( 0 ). If it wasn't an integer, then any digit can be in the ones place.
