Now to solve this addition; let us first make both the denominators equal, to do this we need to multiply both the denominators to number which will bring the denominators equal. In our case denominators are 3 and 4. Let us see below:
3 x 4 = 12
4 x 3 = 12
Now, we know that 12 can be the common denominator in both the fraction. To do so we need to multiply 2/3 to 3 (to both numerator and denominator) and multiply ¼ to 3 (both numerator and denominator). Let us see how it looks like:
However, if you notice closely, multiplying 2/3 to 4/4 will not changing the fraction value, as 4/4 is one and multiplying any number with one will not change the original value.
Now, its easy to calculate the fraction, as we know how to perform fraction addition on equal denominators in the previous link. Let us solve it:
