Answer:
5 9/20
Step-by-step explanation:
4 7/10 + 6/8
Simplify the fractions by dividing the second top and bottom by 2
4 7/10 + 3/4
Getting a common denominator of 20
4 7/10 *2/2 + 3/4 * 5/5
4 14/20 + 15/20
4 29/20
4 + 20/20 + 9/20
4+1+9/20
5 9/20
First, you have to find the common denominator.
It is 40.
But if we change the denominator, you have to change the numerator as well.
We multiplied 10 by 4 to get to 40, so we multiply 7 by 4.

We multiplied 8 by 5 to get to 40, so we do the same to 6:

Now add them:

We get:
58/40
1+18/40 is my answer...
