How do you add #3/7+7/9#?

Answer 1

#1 13/63#

When adding fractions, you first need a common denominator. #3/7 and 7/9# do not have the same denominator, but both 7 and 9 can go into 63. So, #3/7*9/9=27/63 and 7/9*7/7=49/63#. Now they have common denominators, and are still equal to the original fractions because they were multiplied by what equals to 1. #7/7=1, 9/9=1#.
Now, we simply put them side by side and add up the numerators. You do not add the denominators. #27/63+49/63=76/63#

You can now convert to proper fractions.

Answer 2

To add fractions, find a common denominator, which in this case is ( 63 ). Then, rewrite each fraction with the common denominator and add the numerators. ( \frac{3}{7} + \frac{7}{9} = \frac{27}{63} + \frac{49}{63} = \frac{27 + 49}{63} = \frac{76}{63} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
