How do I simplify 4/8 + 5/8 and

7/9 + 6/9?

Thanks

assistance needed

4/8 + 5/8 = 9/8 = 1 1/8

7/9 + 6/9 = 13/9 = 1 4/9

To simplify fractions, you need to find the greatest common divisor (GCD) of the numerator and denominator, and then divide both the numerator and denominator by the GCD. Let's solve the first problem:

1. Find the GCD of 4 and 8. In this case, the GCD is 4 because it's the largest number that can divide both 4 and 8 evenly.
2. Divide both the numerator and denominator by the GCD:

4 ÷ 4 = 1
8 ÷ 4 = 2

So, 4/8 simplifies to 1/2.

Now let's solve the second problem:

1. Find the GCD of 7 and 9. In this case, the GCD is 1 because 7 and 9 have no common factors except for 1.
2. Divide both the numerator and denominator by the GCD:

7 ÷ 1 = 7
9 ÷ 1 = 9

So, 7/9 cannot be simplified further since 7 and 9 are relatively prime (no other factor except 1).

Therefore, the simplified fractions are:
4/8 + 5/8 = 1/2
7/9 + 6/9 = 13/9 (cannot be simplified further)
