When you're dividing fractions ... or multiplying thrm ... they don't need to have the same denominator.

yes alot of times you do

Same as adding, multiplying, and dividing.

Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.

you have to compare the common fractions

Yes, you can.

Find the lowest common multiple of the denominators and adjust the fractions accordingly

Find their lowest common denominator and adjust their numerators accordingly and then add them together. By dividing the sum by 2 will give you the halfway result

Two ways: You can find a common denominator, convert them to equivalent fractions and line up the numerators or you can convert them to decimals by dividing the denominator into the numerator and line them up numerically. The second way is easier.

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.

An easy method for finding a fraction between two fractions would be to take the average of two fractions. You find the average by adding the two fractions together and then dividing the final sum by 2.

Addition or subtraction of fractions require "like" fractions: that is, fractions with the same denominator.

No.

You do nowt

no

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.

There doesn't appear to be any fractions there but to find the LCD of fractions is done in the same way as finding the lowest common multiple of numbers.

Perimeter is taking the length of each side and adding them together. Therefore, if you have the lengths as fractions, you find the common denominator and add the fractions normally.

just find a common denominator and add like you regularly would with fractions.

To compare two fractions, find a common denominator, then convert each fraction to equivalent fractions with that common denominator. Finally, you compare the numerators. 5/6

When adding and subtracting unlike fractions, it is necessary to find a least common denominator. It's the same process as finding an LCM. You can simplify a fraction by finding the GCF of the numerator and denominator and dividing them both by it.

Yes.

Yes you do.

It helps to find a common denominator and multiply both sides of the inequality by this common denominator. That way, you have an inequality without fractions.
