To find the total amount of sugar Joe used, you need to add the amount of white sugar and the amount of brown sugar together.
First, let's add the fractions: 3/4 + 3/8.
To add fractions, you need to have a common denominator. The smallest number that both 4 and 8 can divide into is 8. So we need to rewrite 3/4 and 3/8 with a common denominator of 8.
3/4 can be written as 6/8 because multiplying the numerator and denominator by 2 gives the equivalent fraction.
3/8 stays the same as it already has the denominator of 8.
Now, you can add the two fractions: 6/8 + 3/8.
When the denominators are the same, you simply add the numerators: 6 + 3 = 9.
The final answer is 9/8 cup of sugar in total. However, since 9/8 is an improper fraction, you can simplify it.
To simplify, you divide the numerator by the denominator: 9 รท 8 = 1 remainder 1.
So, Joe used 1 and 1/8 cup of sugar in total for his cake.
