Explain adition fraction when the denomenator are the same and different?

Question

Plz give me examples for both.Same denomenator and different.

Answer 1

In fraction if the denominators are the same, just add the numerators and copy the denominators, then reduce to lowest term as needed.

Example: 1/2 + 3/2 = 4/2 or 2
The numerators are 1 and 3, adding them will give 4. Then just copy the denominator which is 2. That makes it 4/2, which you need to reduce to lowest term. So 4 divided by 2 (to reduce to the lowest term) so the answer is 2.

If the denominators are different, then find a common denominator (the least number that can be divided by both denominators) then divide it with the denominator and multiply with the numerator. Then when your numbers are already expressed on fraction with the least common denominator, proceed to adding the numerators and copy the denominator.

Example:

1/2 + 2/3 (the common denominator will be 6)
>>1/2 becomes >> 6 divided by 2 = 3 X 1 = 3 -->> 3/6
>>2/3 becomes >> 6 divided by 3 = 2 X 2 = 4 -->> 4/6

Proceed to addition:
3/6 + 4/6 = 7/6 (divide 7 by 6 to get the lowest term) = 1 and 1/6 is the answer.

Good luck!♥

Answer 2

if you have 2 fractions with the same denominator, just add the numerators together (ie: 3/4 + 2/4 = 5/4). it's the same as 2+3=5 which is just 4/2 + 6/2 = 10/2, just simplified. if there are different denominators (ie: 3/4 + 1/3), you can't just add the top and bottom because if look at the answer (4/7, the answer doesn't make sense because it's less than 3/4. that's why you need to put it in common denominator terms so it becomes 9/12 + 4/12 = 13/12. hope that helps.

Answer 3

For same denominators, just add up the numerator and retain the denominator.

for example,
(2/9) + (5/9) = (7/9)


For different denominators, find the lowest common multiple of the denominator.

e.g.
(2/3) + (4/15)
= (10/15) + (4/15)
= 14/15

the lowest common multiple of denominators 3 and 15 is 15.
to arrive at that, the first fraction has to have its numerator and denominator multiplied by 5, therefore arriving at (10/15).

Then just add the fractions up.

Answer 4

multiplying fractions differs from including and subtracting, the place you choose for a consumer-friendly denominator. once you multiply, you multiply in the present day during so it extremely is not suitable if the numerator or denominator are distinctive or the comparable case in point, a million/2 * a million/4 = a million/8

Answer 5

when denominators are the same just add the nominators and the denominator of you re answer is the same. When you have a different denominator you have to find a common denominator and do the same thing.

Answer 6

1) 1/4 + 2/4 = (1+2)/4
= 3/4



[(6/2)*1 +(6/3)*1] / 6
2) 1/2+1/3 =
where 6 is the L.C.M.

= (3+2)/6

= 5/6
