How do you add and subtract dissimilar fractions?
Make the fractions equivalent then subtract
Why does the equivalent fraction make adding and subtracting fractions easier?
You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.
How do you add and subtract by fractions?
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
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,
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
How do you add and subtract dissimilar fractions?
Make the fractions equivalent then subtract
Why are equivalent fractions important when adding and subtracting fractions?
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.

What you need to add or subtract fractions?
You need a common denominator in order to add or subtract fractions.
How can you use equivalent fractions to help you add and subtract fractions with unlike denominators?
Change each fraction to an equivalent fraction with the same denominator. 3/8+5/12= 9/24+10/24=19/24
How do you add mixed numbers?
Find theLeast Common Denominator (LCD)Find the equivalent fractions.Add or subtract the fractions and add or subtract the whole numbers.Write your answer in lowest terms.
Why do you needto find the LCM?
Finding the LCM will help you when you need to add and subtract fractions.
Why is finding the least common multiple important?
It will help when you are trying to add and subtract fractions.
Why should you find a LCM?
Finding an LCM will help when you want to add and subtract fractions.
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,
