Ok so say you have a problem like 3/6 -7/5. You need a common denomonator, in this case 30. you get this by multiplying the first fraction by 5/5 which makes the 'new' fraction 15/30. You then multiply the next fraction by 6/6 to get 42/30.
you then subtract the numeraters and the denominator is unchanged. the answer would be -27/30 (15-42=-27)
What else can I help you with?
How are adding and subtracting fractions similar?
Subtracting a fraction is the same as adding its negative.
How are adding fractions different?
When adding or subtracting fractions their denominators must be the same
What are the rules for adding fractions?
Ensure that the denominators are the same when adding or subtracting fractions.
Are adding fractions the and subtracting fractions the same?
Adding and subtracting fractions are similar processes, but they involve different operations. Both require a common denominator to combine the fractions. When adding, you combine the numerators, while subtracting involves finding the difference between the numerators. Thus, although the steps are alike, the outcomes differ based on whether you are adding or subtracting.
