Atticus has 4 3/5 cups of flour left after making a cake. Kimor needs to borrow 2 2/3 cups of flour to make cookies. How much flour will Atticus have remaining?

Answer 1

To add and subtract fractions, we need to have a common denominator.

First, convert 4 to a fraction with a denominator of 5:
4 = 4/1
4/1 = 20/5

So, Atticus has 20/5 + 3/5 = 23/5 cups of flour.

Next, convert 2 to a fraction with a denominator of 3:
2 = 2/1

Now, convert 2/3 to a fraction with a denominator of 5:
(2/3) * (5/5) = 10/15 = 2/3

So, Kimor needs 10/3 cups of flour.

To subtract, we need to find a common denominator:
23/5 - 10/3

First, find a common denominator of 5 and 3, which is 15.

Convert 23/5 to 69/15:
(23/5) * (3/3) = 69/15

Convert 10/3 to 50/15:
(10/3) * (5/5) = 50/15

Subtract: 69/15 - 50/15 = 19/15

Atticus will have 19/15 cups of flour remaining.

19/15 can be simplified to 1 4/5 cups of flour remaining.
