2.) Given: There are 30 students. 24 are wearing sneakers.

Work: We can figure this out by finding the exact percentage of sneaker-wearers in the class.

To find the percentage, you do 24/30. 24/30 is equal to 80%.


Answer: Joe is wrong. The percentage of students wearing sneakers is 80% and not 70%.


3.) Given: There are 40 people total. 2 women per 3 men.

Work: 2:3 women to men

If we multiply both by 10, we will get 50 people in total.

20:30 = 50

So we need to shrivel this down to 40 by taking out 5 on both sides of the ratio.

50 - 5 - 5 = 15:25 = 40

But the ratio need to be divisible by 2 because of the 2 women that are needed per 3 men. We can do this by moving over one human to the men’s side.

There are 14 women and 26 men. I didn’t use any of the strategies there listed because I don’t even remember what those are. I’m in grade 9. I would say that the ratio table works best because I just used ratios...


4.) Given: Find simplified fraction of silicon. 100%.

Work: Add all things up to find out the denominator for the fraction. They will equal 100.

So the fraction is 28/100.

We can divide this fraction by 4.

7/25

This is the simplified form.


Answer: 7/25
