how do you add mixed numbers with like denominators?

Answer 1

Well, if you mean like 1 2/3 + 2 3/4, you first have to make the denominators alike. So you have to find the lowest common denominator, in this case, 12. So you would multiply 2/3 by 4, and 3/4 by 3. You would then have 1 8/12 + 2 9/12. Then you add that together, which would be 3 17/12. Simplify that and you have 4 5/12, and cannot be further simplified.

Answer 2

add the large numbers and then add the top numbers in the fractions. If the top numbers end up being an improper fraction, work that out. For example:

1 2/3 + 6 2/3 = 7 4/3

= 8 1/3

Answer 3

i will clarify it employing the undertaking 3 7/8 + a million 2/3 = ? the 1st factor to do is to transform the mixed numbers into organic fractions. Multiply the denominator with the help of the entire extensive style section, and upload the effect to the numerator. 3 7/8 --> 31/8 a million 2/3 --> 5/3 subsequent, if the denominators are diverse, you exchange them to the least elementary denominator. interior the occasion above, the least elementary demoninator is 24. 8 x 3 = 24, so 31 x 3 = ninety 3..... so 31/8 = ninety 3/24 3 x 8 = 24, so 5 x 8 = 40.... so 5/3 = 40/24 Now upload the numerators collectively. --> 133/24 Simplify the fraction. 24 is going into 133 5 circumstances, with a the remainder of 13. 13 is a first-rate extensive style, so the fraction will no longer be able to be extra simplified. the respond is 5 13/24

Answer 4

hm... i've also encountered that problem before. I think that you should first add the whole numbers then proceed to adding the numerators. Just copy the common denominator.

ex. 2¼+3¼= 5½
add the 2 and the 3 first. = 5
then add numerators 1 and 1 = 2
then copy the common denominator 4
simplify if possible...
... so it becomes 5½.

Answer 5

You add the numerator ( the top #) together and the whole numbers together. If the numberator becomes bigger than the denominator, then subtract the numerator from the denominatorand add one or how many u gor to the whole number. put the remainder as the new numerator.
Example is:
6/5/3. 6=whole number, 5=numerator, 3=denominator
you subtract five from 3 (5-3=2) which makes two. your new nimber is 7/2/3. 7= whle number, 2=numerator, 3=denominator.

Answer 6

Example: 1 2/5 + 3 1/5 = 4 3/5


Add the whole numbers as you would if they weren't part of the fraction. Same thing for the fractions.

Answer 7

Suppose you have to add 1(1/3) and 3(5/3)
now first do this
1(1/3)= ((1*3)+1)/3= 4/3 and 3(5/3)= ((3*3)+5)/3= 14/3

now add them 4/3 + 14/3 = (4+14)/3 = (18/3)
now since 18 can be divided by 3 so you can write it as 6/1 = 6 i.e. the answer

Answer 8

do you mean like whole numbers like 1 1/8 changing to 9/8. or 3/8 plus 5/8 equals 8/8 equals 1

Answer 9

i think you have to change the mixed number to an improper fraction. then add as normal. im not sure on this tho because i havent had to do that for a long time

Answer 10

add the integer and then add the numerator. the sum of theintegers is the integer of the answer u need and the fraction u get by adding the numerators is the fraction part of the answer.
