Before we can calculate the value of $$\frac{7}{10}+\frac{7}{12}$$, we must create a common denominator. The LCD of both the denominators is 60.

In this step, I will convert $$\frac{7}{10}$$ to a fraction with a denominator of 60.

 $$\frac{7}{10}$$ Multiply the numerator and denominator by 6/6. $$\frac{7}{10}*\frac{6}{6}$$ Notice that multiplying by 6/6 is actually multiplying by 1, which means that the value of the fraction remains unchanged. $$\frac{42}{60}$$

And now I will manipulate $$\frac{7}{12}$$ as well.

 $$\frac{7}{12}*\frac{5}{5}$$ Yet again, we multiply the fraction by 1. $$\frac{35}{60}$$

Since the denominators are the same in both fractions, now we can add them together.

 $$\frac{42}{60}+\frac{35}{60}$$ Add the numerator and preserce the denominator. $$\frac{77}{60}=1\frac{17}{60}=1.28\overline{33}$$
