They are very helpful once you start pre-calculus (i.e. geometry, algebra and trigonometry). You use them alot when adding, subtracting, multiplying, dividing and performing complex equations.
an improper fraction
After you're done multiplying, the GCF will help you determine the simplest form of the answer.
It is important because depending on the problem it is easier to use fractions or decimals. Sometimes the problem is asking for an exact answer, in which case you would keep it in fraction form.
It is not as helpful when multiplying very small numbers because the numbers are going to be very east to answer. That is why estimating is not as helpful when multiplying very small numbers.
it is helpful because if you become a carpenter you will know how much carpet you need or for other jobs turning mixed number into improper fractions is just helping you learn a bout mixed number even more
The GCF is helpful in reducing fractions. The LCM is helpful in adding and subtracting unlike fractions.
It can be very helpful, so the question is inappropriate.
This can be especially helpful if you are adding or subtracting fractions, so the bottom number on both fractions will be the same
It is not always helpful.Some people may find it helpful when comparing fractions. By converting them into percentages they are made into like fractions: all with the denominator 100.
No, it is not.
They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.
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.
Because it helps in reducing fractions to their simplest terms and finding the lowest common denominator when adding or subtracting fractions
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.
