Answer:

For this question, you can make the denominators the same to get the answer.

LCM of 7 and 9 = 63

\frac{6}{7} + \frac{4}{9}  = \frac{54}{63} + \frac{28}{63} \\

         = \frac{82}{63}

         = 1\frac{19}{63}

Answer:

  82/63

Step-by-step explanation:

The sum can be found using the formula ...

  \dfrac{a}{b}+\dfrac{c}{d} =\dfrac{ad+bc}{bd}

For the given fractions, the sum is ...

  \dfrac{6}{7}+\dfrac{4}{9} =\dfrac{6\cdot9+7\cdot4}{7\cdot9}=\dfrac{54+28}{63}=\boxed{\dfrac{82}{63}}

_____

<em>Additional comment</em>

When the denominators have no common factor, the least common denominator is their product, as here.

What does 2 3/5 divided by 1 1/25 equal
Nataliya [291]

Alright, so let's make 2 3/5 into an improper fraction.

2 x 5 = 10 + 3 = 13

So 13/5 / 11/25.

Keep, change, flip rule: 13/5 x 25/11.

Now you multiple the numerator and denominator from both fractions. (I'm not going to do the math for you. Hope this helped and sorry if my explanation is...yeah.)
