Ratios and Percents, a la Shmoop. Poor Milton. He tries.
- 00:10
But usually… he fails. Like bad hair, Milton is teased daily.
- 00:19
Yesterday he was ridiculed an impressive 720 times just about the toilet paper stuck to
- 00:24
his shoe. By referring to this pie chart, can you determine

how many times he was teased about his camouflage pants?

Here’s a handful of choices:
- 00:37
Well, if 720 teasings represents 25% of the total number of derisive remarks aimed in
- 00:53
Milton’s direction in a single day… …then we should be able to find that total
- 00:57
number with the following equation: 720 divided by x equals point-two-five.
- 01:07
In this equation, x represents the total sum of teasings.
- 01:11
Solving for x we divide 720 by .25 to
- 02:20
get 2,880. Wow. We’re guessing he struggles in the
- 02:26
lady department. So now all we need to do is calculate 10% of 2,880.
- 02:50
10 percent, or point-one times 2,880 equals 288.
- 02:59
Answer “D” – you’re our man. 288 negative comments about the camo pants.
- 03:06
Oh, Milton. How hard would it be to throw on a pair of blue jeans?
