So this is your problem: 3/8 + 3/4

To add these fractions together, you need a **common denominator**. To find the common denominator, you need to find the greatest common factor of 4 and 8, which happens to be 8.

You then need to convert both fractions into fractions with a denominator of 8. 3/8 is all set, so all you need to do is to convert 3/4 into an equivalent fraction with a denominator of 8.

You can do this by setting up a proportion: 3/4 = x/8. Cross multiplication gives you: 4x = 24, x = 6. So, **3/4 = 6/8**.

Plugging this back into the original expression: **3/8 + 3/4 = 3/8 + 6/8**. All you need to do now is add the numerators, which gives you a sum of **9/8**, which is the same as mixed number **1 * 1/8** or the decimal **1.125**.
