By finding their common denominator & adding the top numbers of-the fractions. : )
multiply the denominator by the whole number, then add the numerator, the denominator is the same as the mixed numbers denominator
You multiply the denominator by the whole number the add the numerator and you keep the denominator the same.
Yes, you can.
Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes
If the denominator is the same, you just add the numerators - just as with plain numbers.
add numerators
You add the numerators and put over the denominator.

You re-scale them so that the denominators are the same.
You multiply the denominator by the whole number the add the numerator and you keep the denominator the same.
When subtracting you have to make sure that the second numerator is multiplied by -1 so the equation turns into adding. When you add and you already have a common denominator you add the numerators and leave the denominator the same.
Yes, you can.
Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes
Rational and Irrational Numbers
Every time. The sum of two rational numbers MUST be a rational number.
