You re-scale the fractions so that their denominators are the same. The the numerator of the answer is the sum of the numerators of these new fractions and the denominator is the new denominator.
Thus 1/3 + 2/7 = 7/21 + 6/21 = (7 + 6)/21 = 13/21.
To model addition and subtraction of mixed fractions, first convert each mixed fraction into an improper fraction. Then, find a common denominator to align the fractions. Once they have a common denominator, perform the addition or subtraction of the numerators while keeping the denominator the same. Finally, if needed, convert the resulting improper fraction back into a mixed fraction for the final answer.
The denominator should be the same as the denominator of the fraction.
Simply change the numerator and you will have another - different - fraction wit the same denominator.
Similiar fractions are fractions that have the same 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!

No, you do not.
Any fraction with the same numerator and denominator is equal to ' 1 '.
If the numerator and denominator are the same, the fraction simplifies to 1. And you should be able to subtract 1!

Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
No!If numerator and denominator have the same signs the fraction is positive.If numerator and denominator have opposite signs the fraction is negative.
