Explain why it is necessary to rename 4 1/4 if you subtract 3/4 from it

To understand why it's necessary to rename 4 1/4 when subtracting 3/4 from it, let's break it down step by step.

First, let's express 4 1/4 as an improper fraction. To do this, we need to multiply the whole number, 4, by the denominator of the fraction (4), and then add the numerator (1). So, 4 1/4 can be rewritten as (4 * 4 + 1)/4, which simplifies to 17/4.

Next, we need to subtract 3/4 from 17/4. To do this, the fractions need to have the same denominator. In this case, the denominators are already the same, so we can subtract the numerators directly. 17/4 - 3/4 equals (17 - 3)/4, which simplifies to 14/4.

Finally, we need to simplify the resulting fraction, if possible. We notice that both the numerator and denominator are divisible evenly by 2. So, we can simplify 14/4 by dividing both the numerator and denominator by their greatest common factor, which is 2. Doing this, we get 7/2.

Therefore, the final answer to the subtraction problem is 7/2.
