4 3/4 - 2 2/3 = ?
When adding or subtracting fractions, the denominators must be the same. We need to find a common denominator for the fractional portions of each mixed number. In other words, we are looking for equivalent fractions for 3/4 and 2/3. By listing the multiples of 4 and 3, we see that 12 is common to both numbers do we can use 12 as our common denominator.
4, 8, 12, 16, 20...
3, 6, 9, 12, 15....
4 3/4 If we multiply the numerator and denominator by 3, our equivalent fraction is 4 9/12.
2 2/3 If we multiply the numerator and denominator by 4, our equivalent fraction is 2 8/12.
Now we can subtract
4 9/12 - 2 8/12 = 2 1/12.
