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.

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.

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.

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.

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.

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

You first have to convert the fractions so that the denominators are the same.

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.

Like fractions can be ordered according to their numerators alone. You can ignore the denominators for the process.

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).

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.

If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).

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.

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 !

Multiply the numerators together. Multiply the denominators together. Reduce, if possible. The answer when multiplying fractions together will always be lower than either.

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.
