<h3>Part 1 - Adding fractions with unlike denominators</h3>

If two fractions have unlike denominators, we first need to give both of them the same denominator, since we know how to add fractions with the same denominators.

///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\\////\\\///\\\///\\\///\\///\\\///\\\///\\\///\\\///\\\//

Here we have the following fractions: \mathrm{\cfrac{5}{8}+\cfrac{1}{2}}.

First we should find the l.c.m. (least common multiple) of "8" and "2".

The l.c.m. of "8" and "2" is 8. Let's stick it in: \mathrm{\cfrac{5}{8}+\cfrac{1}{8}}.

Now let us consider the following: <em>What did we multiply 2 by to get a result of 8?</em>

Since we multiplied 2 by 4 to obtain 8, we also multiply 1 by 4: 4.

As a result, we obtain \mathrm{\cfrac{5}{8}+\cfrac{4}{8}}.

Now all we have to do is add the numerators.

<u>This is what we obtain as a result: </u> \mathrm{\cfrac{5+4}{8}=\cfrac{9}{8}}.

Notice that the answer is written as an improper fraction, a fraction such that the numerator is larger than the denominator.

Hope this helped you out, ask in comments if any queries arise.

Best Regards!

Now, using property of log

log b^{a} = a log b

log 10^{7}= 7 (1)

log 10^{7}= 7
