Chakell will dance to 12 songs in 30 minutes based on dancing to 4 songs in 10 minutes. To solve this, a proportion is set up comparing the number of songs to time, and then the diagonals are multiplied and divided to isolate the unknown variable. 6 is 12% of 50. To find the percentage, a proportion is set up comparing the part to the whole, the numbers are cross multiplied and divided to isolate the percentage variable. The unit on proportions included food problems, difficulties when first learning, and learning which terms go on top of proportions; however, solving for the unknown variable was easiest.

1. Proportions
By Chakell Phillips

2. Chakell danced to 4 songs in 10 minutes. How many songs will she dance to in 30
minutes
Step 1: set up your proportion.
Then multiply the diagonals
example: 4*30=x*10
x
4*30=x*10
120=10x
12
/10/10
songs
minutes
4
10 30
Step 2: now you have to
solve for x. example:
120=10x
Step 3: divide 10 on both sides
to get x by its self. And you got
your answer

3. 6 is what percent of 50
Step 1: set up your
proportion. Cross
multiply.
6
X*50=6*100
50x=600
12
/50/50
x
100 50
Step 2: solve to get
x by its self.
Step 3: divide 50
by both sides.

4. Unit Reflection
• I liked that some of the problems was about
food.
• I didn’t like when I didn’t know how to do it when
I first learn it.
• The hardest part was learning about is and of
which go on top of which.
• The easiest part was when I solve for x.
