Jamal is making pancakes. He has 6 and three fourth cups of batter, but he needs a total of 12 cups. How much more batter does Jamal need?
How do I go about figuring the above problem out?
12 - 6 3/4 = ______ cups
or
11 4/4 - 6 3/4 = ______ cups
or
12 - 6.75 = ______ cups
This did nothing
1 = 4/4
If you cut a pizza into four equal pieces, each piece is 1/4 of the pizza. You have four fourths of the pizza.

To solve this problem, you need to find the difference between the amount of batter Jamal already has and the amount he needs. Let's break it down step by step:
Step 1: Convert the mixed number 6 and three fourths (6 3/4) to an improper fraction.
To do this, you multiply the whole number (6) by the denominator (4), then add the numerator (3) to get the new numerator. The denominator remains the same.
6 x 4 + 3 = 27
So, 6 3/4 is equal to 27/4.
Step 2: Find the difference between the amount of batter Jamal has and the amount he needs.
To do this, subtract the amount of batter Jamal already has (27/4 cups) from the amount he needs (12 cups).
To make the subtraction easier, we need to have the same units.
Since 1 cup is equal to 4/4 cups, we can convert 12 cups to an equivalent fraction with a denominator of 4:
12 x 4/4 = 48/4
Now we can subtract:
48/4 - 27/4 = 21/4
Step 3: Simplify the fraction (if necessary).
The fraction 21/4 cannot be reduced any further. So, Jamal needs 21/4 cups more batter.
In summary, Jamal needs 21/4 cups more batter to make a total of 12 cups.
