How can you tell a fraction is greater than another?
Two ways: If they're unlike fractions, convert them to like fractions with a common denominator and compare numerators. Convert them to decimals by dividing their denominators into their numerators and see which is greater.
How are equivalent fractions used in renaming when subtracting?
When subtracting one fraction to another, one or both fractions are renamed so that they have the same denominators. Then the result of the subtraction is the equal to the subtraction of the numerators divided by the common denominator.
Why is reciprocal of a fraction less than 1 is always greater than 1?
Proper fractions are less than one.. Their numerators re less than their denominators. Their reciprocals have numerators greater than their denominators, making them improper. Improper fractions are greater than 1.
How do you borrow when subtracting a fraction?
If you have common denominators, then you subtract the numerators of the fraction in the same way you do any other numbers. So yes you can borrow.
How are equivalent fractions used when subtracting unlike fractions?
First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification.For both fractions find an equivalent fraction whose denominator is this common denominator.Carry out the subtraction on the new numerators to give the numerator of the answer.Simplify the result for the final, simplified answer.First you find a common multiple of the denominators.

How you multiply fractions?
To multiply fractions, multiply the numerators by the numerators, and the denominators by the denominators, and then (if possible) simplify the resulting fraction. For example, 2/3 x 4/5 = 8/15
How do you subtract fraction if the if the numerators is the same?
You first have to convert the fractions so that the denominators are the same.
Does adding numerators and denominators work in fraction addition?
To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.
How do you order like fraction?
Like fractions can be ordered according to their numerators alone. You can ignore the denominators for the process.
How to do plus in fraction?
To add fractions, you must make sure that the denominators of both of the fractions are the same, then you add the numerators. Example: 1/6 + 3/6 Since the denominators are the same, just add the numerators. The answer is 4/6 (It is 1/2 when simplified).
What are the denominators and numerator's of 81?
Fractions have numerators and denominators. 81 isn't a fraction. You could write it as "81/1" if you want to. Then the numerator is 81, and the denominator is 1.
What are the rules in subtracting similar fraction?
If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).
What do you notice when the denominators in two fractions are the same?
You can represent the two fractions with one fraction with a numerator equal to the sum of the two individual numerators (with sign) and a denominator equal to just one of the two denominators.
What is relationship between numerators and denominators of factors and numerators and denominators of product?
this is a tricky question but the relationship between the numerators of the product is that they both fractions - and for the next question is that in some fraction their is aways going to have the same denominator that never changes or DONT CHANGE AT ALL !
How can you tell a fraction is greater than another?
Two ways: If they're unlike fractions, convert them to like fractions with a common denominator and compare numerators. Convert them to decimals by dividing their denominators into their numerators and see which is greater.
How do you multiply a fraction?
Multiply the numerators together. Multiply the denominators together. Reduce, if possible. The answer when multiplying fractions together will always be lower than either.
How do you add and subtract fractions in math?
You need common denominators. Then add or subtract the numerators. If the answer is an improper fraction it is common practice to reduce it to a mixed number.
