3. First, turn the fractions into improper fractions
11/8 + 11/4
Since we can't divide 11 by 2 to make the denominator of the first fraction 2, let's multiply both sides of the second fraction by 2 instead.
11/8 + 11*2/4*2 = 11/8 + 22/8
<u>33/8, or 4 1/8</u>
(I already answered numbers 4 and 6 in a previous question you asked)
5. 1 1/2 + 2 3/4
Obviously, we'll start by converting the fraction into improper fractions.
3/2 + 11/4
Multiply both sides of the first fraction by 2
3*2/2*2 + 11/4 = 6/4 + 11/4 = 17/4
<u>17/4, or 4 1/4</u>
Answer:
3.75
Step-by-step explanation:
Answer:
Therefore the maximum number of books sold by the bookstore would be = 120 + 25 = 145 books.
Therefore the minimum number of books sold by the bookstore would be = 120 - 25 = 95 books.
Step-by-step explanation:
i) Average of 120 books sold per week.
ii) the value can vary by as many as 25 books.
iii) therefore the maximum number of books sold by the bookstore would be = 120 + 25 = 145 books.
iv) therefore the minimum number of books sold by the bookstore would be = 120 - 25 = 95 books.
-3pa - 9b - 18pc
For starters, you know that you can't take away any of the letters from the equation because none of the three have the exact same letter; however, they all have something they can be divided by and that is -3.
It would be -3 instead of just 3 because the equation itself starts with a negative. (you could probably do it anyways with just 3, but you'd end up taking out a negative one, anyways, so what's the point?)
Now, you would have: -3 ( pa + 3b + 6pc )
That is truly all you can take out. So, that would end up being your answer since all you can really do is simplify.
