When the numerator is less than the denominator. For example 1/2, 3/4, 18/27, ...
Just working with fractions if the coefficient of x is not an even number, however I would not call it a disadvantage because fractions are beautiful numbers.
The bottoms number like 3/4 4 would be the denominator heres a problem 6/12 + 2/12 the bottom numbers are the same
How would we do it well remember a unit fraction always has one as a numerator. So 2/3 would be 1/3 plus 1/3. These are the unit fractions. It's got a 1 is a numerator all right 5/6 would be a 1 6.
You must have 2 fractions or more to have unlike fractions. They are fractions with different denominators such as 7/8 and 1/2. Like fractions would have the same denominator like 7/8 and 4/8.
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, the way you wrote the number is the standard form for your example. However, one would usually write it with comma separators as: 8,900
Use fraction to express a number less than one
What is one situation you would use fractionsto espress a number less than one?
Whether fractions work better than decimals or less as well is very much a question of your preference.
The fraction 1/3=0.3333333... In this case it is better to use fractions just like in all cases. There will be no case when decimals will work better than fractions however, if a test says to use decimals; USE THEM!
it would not be a good time to estimate mixed numbers is when both of the fractions are not a mixed number
To add and subtract unlike fractions.
When you are seeing how many of the pizza has been eaten. I'm serious by the way
Express the mixed fraction as an improper fraction and then proceed as you would with ordinary fractions. If the answer is an improper fraction, then remember to convert to a mixed fraction.
When both of the fractions are not even mixed numbers!
Yes it is acceptable unless it reads express in fractions. But most times it would be a decimal. When you step on a scale it doesnt tell you that you read 1353/4 It tells you you read 135.75 pounds
When you are trying to reduce fractions.
you would convert the mixed numbers into fractions where the top number is greater than the bottom number, then multiply both the numerator and the denominator by a number that makes the denominators the same.
