Answer:

\frac{m}{n}

Step-by-step explanation:

Setting it up as a fraction will help us see the simplification process a bit easier.

\frac{am}{an}

a/a = 1, so they cancel each other out, leaving us with simply

\frac{m}{n}

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

Kaylin bought a soda and two bags of popcorn for $3.00 . HER brother bought three sodas and a bag of popcorn for $6.50
Veseljchak [2.6K]

Answer: price of soda (a) = $2 and price of popcorn (b) = $0.5

Step-by-step explanation:

Let's denote soda = a and popcorn = b

Kaylin bought a soda and two popcorn, writing out an equation for this would be

a + 2b = $3...........equation (i)

And her brother bought 3 sodas and 1 popcorn.

3a + b = $6.50..........equation (ii)

From equation (i),

a + 2b = 3

Making a the subject of formula,

a = 3 - 2b......equation (iii)

Using substitution reaction, put equation (iii) into equation (ii)

3(3 - 2b) + b = $6.50

9 - 6b + b = 6.50

9 - 5b = 6.50

Collecting like terms,

5b = 9 - 6.50

Divide both sides by 5,

b = 5.

Put b = 5 into equation (i)

a + 2(0.5) = 3

a + 1 = 3

a = 2

Therefore, the price of soda is $2 per one and $0.5 for each popcorn.
