Try the practice questions first and check your answers
with those given.
Then, answer the “real” questions, #1-8. Show your
work on the organizer you received in class.

Convert the mixed number to an improper fraction.
Then, multiply by the reciprocal of the second fraction.
To convert to an improper fraction:
1. Remember, ask yourself “how many
thirds are in 2 1/3? There are 7/3s.
2. If you are not sure, draw a picture of 2
1/3, then count the thirds.

3. Multiply the denominator by the whole
number, then add the numerator
(3 x 2 + 1 = 7)

Solve using a picture. Show 2 1/3.
Then divide into sixths.
Next, number or circle groups of 5/6.

Your answer is the number of groups of 5/6
that you have numbered: 2
You only have 4 out of 5
sixths left. So you
cannot make a third
group. Your remainder
is 4/5.
Now, try this on your own. Use pictures or
numbers to solve.

Find the product:
0.25 x 2.37
Find the quotient:
4.67 ÷ .25 =
Click for the answer
using the algorithm.
Find the quotient:
4.67 ÷ .55 = .55 4.67
If the divisor is a decimal, make it a whole number by moving the decimal. Then
move the decimal in the dividend the same number of places. Then divide.
Remember to line up the decimal point in the quotient.
So, if you move the decimal 2 places to the right in .55, it becomes 55.
You must then move the decimal 2 places in 4.67, to make it 467
The new problem is 55 467
Now convert this fraction to a
8.
55. 467.

Now combine the whole
number with the decimal:
Your answer is 8.49

This is the whole number portion
of your answer.
This is your remainder 27/55.
Now try this on your own. Show your work on your worksheet.

8.4 ÷ .32 =
Here are some word problems. Look for key words that tell
which operation is needed to solve the problem. Then, find the
solution and show your work on the worksheet.
5. Sarah needs 2 ¼ yards of material to make one dress for her
daughter. How many dresses can she make from 10 ½ yards
of material?
6. A half pound of raisins was in a jar in Luke’s cabin. He and
his cabin mates ate 2/3 of them. How much of the raisins
did they eat?
7. Mrs. Melton is making ribbons to give to the participants in
the spelling bee. Her roll of ribbon contains 8.4 feet of
ribbon. She wants to make ribbons that are .75 feet long.
How many ribbons can she make?
8. Jason is helping his mother shop at the grocery store. He
needs to buy granola that costs $2.49 per pound. How much
