Part A.
7.8 is a rational number between 7.7 and 7.9.
It is rational because it can be written as a fraction of integers, such as 78/10.

There are 32 students in a class. 12 of those students are girls what percent of the class are boys?

gtnhenbr [62]

You have 12 girls out of 32, so that's 20 boys. Take your amount of boys divided by your total number. So, 20/32 = .625
You want a percentage, so .625 x 100 = 62.5% boys

Answer:

1/2

Step-by-step explanation:

So lets go over what slope is.

The formula for slope is y/x

To find this, we can just count the change in y, and put it over x.

So lets see.

On the graph, we can count that y goes up by one, and that x goes to the right by 2.

So this means our slope is y/x, or 1/2.

This is our answer.

I hope this helps! :)

I included a visual of this as well!
