Can Someone Explain how to do this.
​

Step-by-step explanation:

it's was helpful to you

In order to sum up any two fractions, you need both fractions to have the same denominator.

The denominator is the number under the fractional bar. The denominator of the first fraction is 7. The denominator of the second fraction is what ? It's 3.

7 is different from 3 : 7 ≠ 3

So in order to sum these two numbers, we need their denominator to be the same. How ?

A solution that always work, is simply to multiply each other : 7 * 3

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
