change the denominators to be the same, as you would for addition, so if you have 1/2 minus 1/4 - change the 1/2 to be 2/4 (denominators are the same) to do this multiply denominator by a number that equals the other denominator, in this case 2 and then times it to the top number, hence 2/4. Now you have 2/4 - 1/4, 2-1=1 so the answer is 1/4
What else can I help you with?
How do you add and subtract similar fraction?
Just simply add/subtract the numerators then copy the denominator.
Write a fraction equal to 3 4 that has a denominator of 8 then subtract that fraction from 7 8?
The answer is 1/8.
What is the results when you flip the numerator and denominator of a fraction?
you get a completely different fraction
If two fractions have the same numerator but different denominators is the fraction with the greater denominator greater than or less than the fraction with the lesser denominator?
When the numerators are the same, the fraction with the higher denominator is less than the fraction with the lower denominator. The denominator indicates the size of the "parts" being shown as a fraction, and the higher the denominator, the smaller those parts are!
Can the denominator be a fraction?
YES a fraction can be a denominator.
Why if there are two fraction having different denominator are you are going to find first their least common denominator?
To get the right answer when you add or subtract them.
How to subtract a fraction from a whole number?
Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly
When you add or subtract two like fractions when does the final answer have a different denominator?
Never. You could write a fraction as a mixed fraction if you like and then the mixed fraction would have a different denominator (e.g.: 23/2 = 11 1/2)
How do you add and subtract similar fraction?
Just simply add/subtract the numerators then copy the denominator.
How is subtracting fraction when numerator and denominator is the same?
If the numerator and denominator are the same, the fraction simplifies to 1. And you should be able to subtract 1!
When you subtract fractions do you subtract the denominator?
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
How do you subtract fractions without mixed numbers?
First, turn the fraction into a improper fraction. Then find a common denominator between the two numbers. After this, subtract strait across, but leave the denominator the same.
How do you subtract a fraction?
Find a common denominator (make sure you multiply BOTH the numerator and the denominator) then subtract the numerators and simplify if necessary.
Can you subtract a fraction with the same denomintor and get a different denominator?
Only after simplification. If you subtract numbers with the same denominator, you have to put the original denominator in the result, but you can later simplify this, in some cases. A simple example: 3/4 - 1/4 = 2/4. Same denominator, but this can be simplified to 1/2.
How do you subtract mixed fractions when they have the same denominator?
The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.
What is a fraction with a denominator that has a different value?
It is a different fraction!
Why do fractions need a common denominator when adding subtracting?
In order to add or subtract one fraction from another, they must have a common denominator, or the same denominator. That's because it's impossible to add two fractions that have a different number of parts.
