Now imagine 4 birthday cakes!
11
The cakes are just rectangles that you cut into pieces!
12
We’ve got to cut up the cake to feed our friends!

There are other ways to name this mixed number too. What if the cakes looked like this?

21
8 + 3 = 11. The cakes are cut into 8 slices. So I have 11 8 !!!!!!!!!!!!!!! 2
22
There are other ways to name this mixed number too. What if the cakes looked like this?

DUDE! The fraction test is going to be a breeze. Help me! Help me! Everyone understands but me! AHHHHH!.
30
DUDE! Why so tense? Nervous about math? YES! Duh!
31
Fractions, decimals, and percents are just ways of describing the exact same thing. Nervous about math? YES! Duh! They all describe numbers that are less than 1. $1.00.75. 50.25 4/4 3/4 2/4 1/4 4 out of 4 quarters 1 out of 4 quarters 2 out of 4 quarters 3 out of 4 quarters
32
Imagine a dollar’s worth of dimes. TEN dimes equal 1 WHOLE dollar Nervous about math? YES! Duh! $1.00.90.80.70 10/10 9/10 8/10 7/10 9 out of 10 dimes 10 out of 10 dimes 8 out of 10 dimes 7 out of 10 dimes
33
10 dimes equal 1 WHOLE dollar. 4 quarters equal 1 WHOLE dollar. Nervous about math? YES! Duh! I do like money.
34
Percents are even easier when you already have the decimal. Nervous about math? YES! Duh! They even look the same. $.75 $.50 $.25 It’s 75% of $1.00 It’s 50% of $1.00 It’s 25% of $1.00 75 100 50 100 25 100
35
Now, if you had 5 of a dollar how Nervous about math? YES! Duh! much money would you have? 10 I would have 5 dimes which is 50 cents…OH!.50.
36
Now, if you had 3 of a dollar how Nervous about math? YES! Duh! much money would you have? 10 I would have 3 dimes which is 30 cents…or.30.
37
I RULE!!!
38
Now, if you had 4 of a dollar how Nervous about math? YES! Duh! much money would you have? 10 I would have ____ dimes which is ____ cents…or.____
39
Now, if you had 1 of a dollar how Nervous about math? YES! Duh! much money would you have? 4 The 4 means quarters so…you basically said I have 1 out of 4 quarters…so I have…
40
Now, if there’s a super simple way to change fractions into decimals and percents Nervous about math? YES! Duh! Take a fraction like 10 25 Just multiply the bottom number by 4 to make it 100. 10 25X 4100 ?
41
Just remember, if you multiply the bottom number by 4 you have to multiply the top number by 4 also. Nervous about math? YES! Duh! 10 25X 4100 40 X 4
42
Nervous about math? YES! Duh! That’s great. Another thing that confuses me is how to ell which fraction is bigger when the denominators are different. This guy needs a new haircut. Maybe I’ll tell him after he learns fractions. 1 5 3 10 Which is the bigger fraction?
43
A super secret way to do this…is to take your calculator and divide the top number by the bottom number Nervous about math? YES! Duh! 1 divided by 5 is.20. 3 divided by 10 is.30.
