Sagot :
Answer:
Step-by-step explanation:
It actually depends on the given fraction let's say it is
1/3+1/4 by finding the lcm it will be 12
and the solution will be
4/12+3/12=7/12 in t his case you cannot eliminate the fraction on the one side of the equation you can only convert it into improper fraction.
But getting the lcd was needed to make an opperation(sum and difference) in both fraction that has different denominators.
