Explanation:
Find a common denominator.
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.
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.
