two and one fourth minus one and three fourths equals

Answer 1

The answer should be 1/2

Answer 2

1/2

Explanation:

2 1/4 - 1 3/4 Because the denominator are already the same, all you have to do is make it a mixed number and subtract. To do that you multiply the whole number to the denominator and add that new number to the numerator. So you would then have.

9/4 - 7/4

Keep the denumerator the same and subtract the numerators.

2/4

Then simplify

1/2
