Subtracting Mixed Numbers with Regrouping

Subtracting Mixed Numbers with Regrouping

Example: Subtract 4 1/4 - 2 3/4

Step 1: Subtract the whole numbers.
Subtract the whole numbers first:
4 - 2 = 2

Step 2: Compare the fractions.
The fraction 1/4 is smaller than 3/4, so regrouping is needed.

Step 3: Regroup one whole number.
Take 1 from the whole number 2 and convert it into a fraction:
1 = 4/4
Now the mixed number becomes:
1 5/4

Step 4: Subtract the fractions.
Subtract the fractions: 5/4 - 3/4 = 2/4
Simplify the fraction: 2/4 = 1/2

Step 5: Combine the results.
The final answer is:
1 1/2
