Answer:

13/4

Step-by-step explanation:

the method is pretty easy.we find the LCM of the denominator and then see in how many times it comes in the denominator we then multiply the numerator of the given denominator by its multiple of the LCM .Lemme show u how:

LCM of 2 and 4 is 2

hence,(3*1/4*1)+(5*2/2*2)

=3/4+10/4

now the denominators are common so we can add them up it becomes:

=10+3/4

=13/4

First you need to find a common denominator.
So in this case its 4
And whatever you do to one number to do the the other
So 4 x 1 is 4 so you have to multiply its numerator by 1 which would be 3
And 2x2 is 4 so multiply it’s numerator by 2 which is 10
Now your equation would look like this :
3/4 + 10/4
Now the easy part, adding

3 + 10 = 13
And you keep the denominator the same
So it would be 13/4
Now you need to simplify 13/4 to 3 1/4

So your answer would be 3 1/4
