You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
When you're dividing fractions ... or multiplying thrm ... they don't need to have the same denominator.
you flip the last (second) fraction, and then you change the divide sign into a times sign. You can then times the fractions from there. You do not need the same denominator to times fractions.
Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
The same numerator or the same denominator.
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.
idk you need to find it yourself * * * * * equivalent fractions.
I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.

Not always but they need to have the same denominators when adding or subtracting them.

It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.

Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
exactly you got it you dont need help :)
Yes, bankers use fractions because fractions are the same as percentage. and they need percentage for exact change and for knowing how much money is in the safe.
