You find the least comon multiples of the fractions' denominators.
By finding the lowest common multiple of the fractions with different denomiators that need to be added or subtracted
If its a fraction then we can change the numerators and denominators upside down .This is in case of fraction.
By finding the lowest common multiple of the denominators
If the denominators (bottom numbers) are the same (eg. 11/6 - 7/6) you just subtract the numerators (top numbers) eg. 11-7=4 so 4/6. If the denominators are different you have to find equivalent fractions where the denominators are the same.
You need to find the least common multiple of their denominators.
multiply the nominator and denominator of each fraction by the denominator of the other fraction
first simplify the fraction then multiply the denominators times the numerators and see if they are equal
Find the least common denominator and convert them to equivalent fractions so that the denominators are the same. Choose the one with the greatest denominator.
Yes, 'fractions' with different numerators can be added, but not with different denominators. In the case where you have different denominators, you must find the LCM (lowest common multiple).
By finding the lowest common multiple of the denominators.
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
By finding the lowest common multiple of the different denominators then rearranging the numerators and denominators accordingly.
