1. Unit 7 Math Review

2. What are
Equivalent Fractions?
• Fractions that are equal. The number of
equal pieces are different, but the fraction’s
value (out of the whole) is the same.
• As an example, think of a two-slice pizza that has
then been cut into four slices, six slices, etc. The
size of the original pizza hasn’t changed!

3. Find Equivalent Fractions

• What is a fraction equal to 2/5 ?
• What is a fraction equal to 15/30 ?

Number Stories
Courtney was tired of her collection of 12 teddy
bears. She sold 3/4 of them at a yard sale.

17. Probability
A sack contains You reach into the sack
and pull out a marble
4 red marbles without looking. About
what fraction of the
3 green marbles
time would you expect
2 black marbles to pull out a black
marble?
5 white marbles
2/14 or 1/7

18. Probability
A sack contains What percent chance do
you have of pulling out a
4 red marbles red marble?
3 green marbles
(Use the calculator on your
2 black marbles widgets to help you!)
5 white marbles
4 / 14 x 100 = ?
Answer: 28.5%

20. Which Fraction is Larger?
5/6 11/12
or
11/12 is bigger because it is only
1/12 away from being a whole.
5/6 is 1/6 away from being a whole.
Twelfths are smaller pieces than sixths.
In other words, 1/12 is smaller than 1/6,
so 11/12 is the larger fraction.

21. Making Spinners
Color the spinner so
that it will land on red
about 50% of the
time.
Color the spinner so
that it will land on
blue about 1/4 of the
time.
What fraction and percent of the spinner is yellow?
1/4 or 25%
