Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
Why is it inaccurate to simplify add the numerators if two fractions with unlike denominator?
Because that is not how addition of fractions is defined.
When do you use LCM in math?
When you want to add or subtract unlike fractions.
How are like fractions and unlike fractions different?
Like fractions have the same denominator, unlike fractions don't.
When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.
Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
What problems can be solved using gcf and LCM?
Finding the LCM will make adding and subtracting fractions easier.
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
How do you add fractions with unlike denomanators?
You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal fractions.
Adding unlike fractions?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Why do you have to turn unlike fractions into like fractions to add or subtract?
because its just one of the rules of math :)
Why is it inaccurate to simplify add the numerators if two fractions with unlike denominator?
Because that is not how addition of fractions is defined.
How do you add fractions with unlike denometiors?
You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
What is a situation where you would use LCM?
To add and subtract unlike fractions.
When do you use LCM in math?
When you want to add or subtract unlike fractions.
Why do you need to use common denominator?
To get the right answer when you add or subtract unlike fractions.
