like everything in math, fractions WILL pop up down the road. Fractions are needed to represent part of the whole unit. For example, a whole Pizza is one unit, but if you slice it into eight pieces, each piece represents 1/8 of the whole pizza. You can now share fractions of the pizza with friends.
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.

The answer depends on what you need t do with the fraction.
You need to learn it, so you can learn Greatest Common Factor, which you need to reduce fractions.
Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!
You need a common denominator in order to add or subtract fractions.
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
Unlike fractions have denominators that are unequal, and therefore cannot be added or subtracted. If two fractions need to be added or subtracted they must first be converted to like fractions.
You need a common denominator for both.
Yes. You need common denominators if you want to:Add fractionsSubtract fractionsCompare fractions ("which is larger?")You do not need common denominators to multiply or divide fractions. Thus, in the case of fractions, multiplication and division is actually easier than addition and subtraction.
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.
I need help in how to convert fractions to decimals
No, unless you want fractions over fractions.
You don't need a common denominator to divide fractions.
No.
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.
They need to know about decimals, fractions, and percents because they need to know the exact measures of the things they are designing.
