The recipe calls for 4 3/4 cups of flour of flour she has 2 2/3 how much more flour does she need?

Step-by-step explanation:

4 3/4 - 2 2/3 = ?

When adding or subtracting fractions, the denominators must be the same. We need to find a common denominator for the fractional portions of each mixed number. In other words, we are looking for equivalent fractions for 3/4 and 2/3. By listing the multiples of 4 and 3, we see that 12 is common to both numbers do we can use 12 as our common denominator.

4, 8, 12, 16, 20 ...

3, 6, 9, 12, 15 ...

4 3/4 If we multiply the numerator and denominator by 3, our equivalent fraction is 4 9/12.

2 2/3 If we multiply the numerator and denominator by 4, our equivalent fraction is 2 8/12.

Now we can subtract

4 9/12 - 2 8/12 = 2 1/12.

So Cameron needs an additional 2 1/12 cups of flour.

2 1/12 more flour

Step-by-step explanation:

so we need to find the difference of the two so we do 4 3/4 - 2 2/3, but we need to find the common denominater which is 12. now it becomes 4 9/12 - 2 8/12 (because we multiply 3/3 to 3/4 and 4/4 to 2/3) which becomes 2 1/12 because 4-2 is 2 and 9/12 - 8/12 is 1/12.
