Question

when adding fractions, if the bottom is the same. you dont add those. they stay the same and only the top is added?

Answer 1

Let us add the following fraction

`\frac{3}{7\text{ }}+(1)/(7)`

As you asked the bottom, known as the denominator for both fraction are the same. So when such fractions as a rule of the thumb, the denominator remains the same while the numerator adds up.

`(3)/(7)+(1)/(7)=(4)/(7)`

Alternatively, we can find the L.C.M of both fractions and add them up

So the answer is yes or True
