2. 1/2+4/5 To find the answer to this problem there are 2 steps. First you must change both fractions so the both have the same denominators. You have to find the common denominator between the two. Once the common denominator is found you must multiply the numerator by the same number you used to change the denominator. ½ would become 5/10 and 4/5 would become 8/10. 1 / 2 Denominator Numerator
3. 5/10 +8/10 Once you have finished changing the denominators, you add the two fractions together. Every single time you add a fraction though, you must keep the denominator the same. So, the /10 part of this fraction will still be /10 in the answer. Once you have done this you add the numerators together (5+8=13). Then, you put the answer from adding the numerators on top of the denominator and that is your answer. Once you have found your answer (13/10 or 1 3/10) you have to simplify your answer. With this answer though you don’t have to.
4. 7/8-3/4 When subtracting fractions you do pretty much have to do the same thing that you do when adding, except you are subtracting. You have to find the common denominator. In this problem the common denominator is 8. Once you have found the common denominator both fractions should have that number as the denominator.
5. 7/8-6/8 When you are changing the numerator remember to multiply with the same number you used to multiply the denominator with When you denominators have been changed you have to change the numerator.
