Answer: No, the cook "dose" not. The cook needs 1/12 more cups of flour.

Step-by-step explanation: First, we should find a common denominator for 2 2/3 and 2 3/4. We can also ignore the 2 in front of both fractions, as this will not matter since 2 is present in both fractions as a whole number.

The LCM of 3 and 4 is 12 (3*4 = 12)

Let us start with the first fraction, 2 2/3.

12/3 = 4

We need to multiply 2 by 4.

2*4 = 8


Therefore, 2 2/3 is equivalent to 2 8/12.

Now for the second fraction, 2 3/4:

12/4 = 3

We need to multiply 3 by 3.

3*3 = 9

Therefore, 2 3/4 is equivalent to 2 9/12.

2 8/12 < 2 9/12

Therefore, the cook does not have enough flour.


To find how much more flour is needed, all we have to do is subtract 8/12 from 9/12 (ignoring the 2s)

Since the denominator is the same, we can change this to just

9 - 8

Obviously, 9 - 8 = 1.


Therefore, the cook needs 1/12 more cups of flour.
