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.
