How can you add two fractions with denominators of 10 and end up with a sum whose denominator is 5?

A fraction with denominator 10 must have an odd numerator for otherwise its numerator and denominator would have 2 as a common factor and it would be simplified so that it would no longer have 10 as a denominator. So you are adding two odd numerators, both with 10 as the denominator. The sum of two odds is always even, so the result will be an even sum with 10 as the denominator. So in the answer, 2 is a common factor of the numerator and denominator and the answer can be simplified. If there is no other common factor, then the answer must have a denominator of 5.


What is the difference between adding and subtracting fractions?

to add a fraction, get a common denominator, then add the numerators. example: 2/10+4/5 first get common denominators 2/10+8/10 then add the numerators 10/10 (simplify) 1 to subtract from a fraction, get common denominator, then subtract the numerators. example: 4/5-2/10 first get common denominators 8/10-2/10 then subtract the numerators 6/10 (simplify) 3/5


What are the steps needed to add or subtract fractions with unlike fractions?

1. Find a common denominator. If you are not good with numbers and you don't understand what the Least Common Denominator (LCD) is, just multiply the two denominators.2. Find equivalent fractions that have the common denominator found in step 1. If you are not good with numbers, multiply each numerator by the denominator of the other fraction.3. Add or subtract the new numerators.4. Put the new numerator over the common denominator.Numerator = number on the topDenominator = number on the bottomExample: 1/2 - 1/51. Common denominator = 2 x 5 = 102. 1/2 = (1 x 5)/10 = 5/10, 1/5 = (1 x 2)/10 = 2/10So now we have 5/10 - 2/10 instead of 1/2 - 1/53. 5 - 2 = 34. 3/10
