*The ones that are in RED are WHOLE NUMBERS
*Reciprocal-  is the fraction that when multiplied creates a product of 1

10.) Divide

a.) 1 1/12 divided by 2 1/2

You need to turn the mixed numbers into an improper fraction. 1 and 1/2 becomes 13/12 and 2 and 1/2 becomes 5/2. Since you have to do the reciprocal on the denominator, you multiply 13/12 by 2/5 on the top (numerator). Then simplify your answer if needed.

b.) 8/11 divided by 4/5

 Do the reciprocal on the denominator then after you do that step, you put the reciprocal on the denominator and multipy those. Simplify if it is needed, in this case, I simplified it by 4.

c.) 1 3/8 divided by 2 3/4

Do the reciprocal on the denominator then after you do that step, you put the reciprocal on the denominator and multipy those. Simplify if it is needed, in this case, I simplified it by 11 then 2.

11.) In a comedy review, each performer has a 1/4-h slot. How many performers are there in a 2-h show?

My tip for words problems like this is whatever the second number is, that is what's going to be the denominator. I'm not 100% sure it will work all the time, but this is what I've been using for these kind of word problems.
2 divided by 1/4
How many times does 1/4 go into 2?

*Since 2 is a whole number, make it into a fraction by using 1 as a denominator. So it becomes 2 over 1.

12.) It takes 2 1/2 scoops of flour to make one cake. How many cakes do 15 scoops of flour make?

*My tip for words problems like this is whatever the second number is, that is what's going to be the denominator. I'm not 100% sure it will work all the time, but this is what I've been using for these kind of word problems.

           do the reciprocal to the denominator than after you do that, you put reciprocal on the denominator and multiply those. Simplify if you need to.






      do the reciprocal on the denominator than after you do that you put the reciprocal on the denominator and multiply them. simplify them if you need to.

How many groups of 1/4 are in 6?
There are 8 group of 1/4 in 6.

The first thing you do is make the 2 into two over one (2/1). After divide it to 1/4. Make the 1/4 into a reciptical(4/1). Multiply 2/1 to 4/1 so the answer is 8.  


13)

How many groups of 3/4 are in 6?
There are 8 groups of 3/4 in 6. 

The first thing you do is make the 2 into six over one (6/1). After divide it to 1/4. Make the 1/4 into a reciptical(4/3). Multiply 6/1 to 4/3 so the answer is 24/3 then put it into lowest common denominator so the answer is 8.

 Make sure that if you have a question including a whole number  you write it over 1 in order to be able to multiply and for a mixed number, convert it to a a proper fraction (top heavy fraction).

Question`s 1,4 and 9 in the textbook.

1) Anna divided 5/6 by 1/2 and stated that the quotient is 5/12.
        a) What was Anna`s mistake?
        b) What is the correct quotient. Use a diagram to show how you know.

 a) She did it wrong because she had multiplied the 5 by the 1 and the 6 by the 2 instead of doing the reciprocals

b) 5 x 2 = 10
     6    1     6
-----------------
    1 x 2
    2    1

  4) a) Does 2 1/2 divided by 1 1/2 equal 1 1/2 divided by 2 1/2?
b) if the quotients an part a) are not equal, how are they related
2 1/2 and 1 1/2 are improper so you have to make them proper fractions.

So 2 1/2 = 5/2 AND 1 1/2 = 3/2

Those are the proper fractions.

so you go 5/2 DIVIDED by 3/2 and you multiply 3/2 by 2/3 because you need to make a reciprocal.

and what you do to that side you also multiply 5/2 x 2/3 = 10/6 OR 1 2/3

# 2. 1/4 + 5/8

2/8 + 5/8 = 7/8

#9. (the first question with the chart.)
5/6 x 1/2 = 5/12 
the question for that equation is What is 1/2 of 5/6?
