Answer 2

`3/8 + 1/2 = 7/8`

Explanation:

When adding or subtracting fractions, remember that you first need to find a common denominator. This can be found by finding the LCM (Least Common Multiple) or just by multiplying the denominators together.

For this example, we'll use the LCM of 8, because 8 = 8 and 2*4 = 8

Because 3/8 already has the denominator of 8, we dont need to change it.

To change 1/2 so it has a denominator of 8, multiply BOTH the numerator and the denominator so that the denominator = 8.

`1/2 * 4/4 = 4/8`

Notice that 4/4 is equal to one, which means were not actually changing what the fraction is equal to.

Now we can add across the numerator, keep the denominator the same for your answer.

`3/8 + 4/8 = 7/8`
