Cindy has two fourths of a circle and three fourths of a circle. What does she need to make a whole circle?

She already has more than a circle.

Draw a circle and divide it into fourths (like a pizza).

18x14=

To find out what Cindy needs to make a whole circle, we first need to determine the total fraction of a circle that she already has.

Cindy has two fourths of a circle, which can be simplified to one-half (2/4 = 1/2). She also has three fourths of a circle (3/4).

To find the total fraction of a circle that Cindy already has, we can add these fractions together:

1/2 + 3/4 = 2/4 + 3/4 = 5/4

We can see that she has 5/4 of a circle so far.

To make a whole circle, Cindy would need an additional amount to reach a fraction equivalent to 1 whole circle, which is 4/4.

Therefore, to determine what Cindy needs to make a whole circle, we need to subtract the fraction she already has from 1 whole circle:

4/4 - 5/4 = (4 - 5)/4 = -1/4

Based on this calculation, Cindy needs an additional -1/4 (or one-fourth in the opposite direction) of a circle to make a whole circle. This means she needs to remove a quarter of a circle instead of adding it.
