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
Just simply add/subtract the numerators then copy the denominator.
The answer is 1/8.
you get a completely different fraction
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!
YES a fraction can be a denominator.
To get the right answer when you add or subtract them.
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)
Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly
To add or subtract fractions with different denominators, first find equivalent fractions by determining a common denominator. This typically involves finding the least common multiple (LCM) of the denominators. Convert each fraction to an equivalent fraction with this common denominator, and then you can add or subtract the numerators while keeping the denominator the same. Finally, simplify the resulting fraction if possible.
To subtract dissimilar mixed fractions, first convert each mixed fraction into an improper fraction. Next, find a common denominator for the improper fractions. Once you have a common denominator, subtract the numerators and keep the denominator the same. Finally, if needed, convert the result back into a mixed fraction.
If the numerator and denominator are the same, the fraction simplifies to 1. And you should be able to subtract 1!
Just simply add/subtract the numerators then copy the denominator.
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.
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common 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.
Find a common denominator (make sure you multiply BOTH the numerator and the denominator) then subtract the numerators and simplify if necessary.
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.
