you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two

No. Convert them to like denominators and add the numerators.

When you have fractions with like denominators, the larger is the one with the larger numerator.

When adding fractions with like denominators, add the numerators together and put the result over the denominator. Simplify if possible.

They have the same denominators

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.

No. You just have to change it so the denominators are the same, and then it's easy from there!

Like fractions are fractions with the same denominators.

No.

No.

Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).

because they are the same number

No

The same way you would add or subtract whole numbers, leaving the denominators alone.

Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.

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.

By the definition of like fractions, the denominators are the same.

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.

The numerator and denominator of a product of fractions are simply the products of the numerators and denominators respectively. That is, a/b * c/d = (a*c)/(b*d). The denominators can be the same or different - that is irrelevant.

As a review, similar fractions (also like fractions) are fractions having the same denominators

Denominators which have no common factors

Numerator.

40 is the LCD.

multiply the denominators

They are called denominators and numerators!
