Best Answer

Make it to a improper fraction first.

e.g.

1) 3 and 2/3 - 2 and 1/4

-> 11/3 - 9/4

->the Least Common Multiple of 3 and 4 is 12

so

-> (44-27)/12

->17/12

Change it back to a mixed fraction if you want.

You need common denominators. Then add or subtract the numerators. If the answer is an improper fraction it is common practice to reduce it to a mixed number.

SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.

Yes.

To combine the fractions or subtract the fractions. Same method with mixed numbers.

You change the mixed fraction to an improper fraction . Then you find the denominators GCF. Then you subtract. Another reply: Converting to an improper fraction is not really necessary, but converting to a common denominator is. Example: 3 1/2 - 1 1/3 = 3 3/6 - 1 2/6 = 2 1/6. In other words, you can subtract the integer part and the fraction part separately.
