not always,only when you need to
They are useful in reducing fractions and to simplify radicals. They are useful in reducing fractions and to simplify radicals.
You can either simplify then add or add then simplify your answer
You can simplify fractions, sometimes, but you can never simplify whole numbers.
because when we simplify fractions it will give you the correct answer and that is the rule.
When you are reducing equivalent fractions.
The GCF is used to simplify fractions. The LCF is practically useless, since it is always 1.
you can not simplify fractions when one of the ( whole or part) numbers can not be divided by and thing like 11 over 17 could NOT be simplified
In math people simplify fractions because its easier to look at.
No because in order to subtract or add fractions the denominator of the fractions must be the same and if they are not then the lowest common denominator of the fractions must be found. Having subtracted or added the fractions then it may be possible to simplify the result.
