Answer: yes when your adding or subtracting fractions you must find the common denominator between the two before you continue.
Step-by-step explanation:
Example: 2/4+3/2
Find the common denominator. ( in this case the common denominator is 4)
We keep the first fraction as it is cause it has the denominator 4 and we multiply the second fraction by 2 up and down to get a denominator of 4. The equation becomes 2/4+6/4
Now you add the numerators and you got your answer ( don’t forget to simplify)
The answer after adding in this case is 8/4 and when simplified it is 2
