Good morning I tried to simplify the problem below and I am getting some weird results can anyone help me break this down ( simplify in detail )
1/ 1/a + 1/b=
thank you in advance.
1/1/a is the same thing as writing 1 divided by 1/a. When we divide by a fraction, we multiply by its reciprocal, so the operation becomes 1 * a which is just a.
Now we have a + 1/b. In order to add these two, we have to have a common denominator. Since b is the lowest common denominator, multiply both the numerator and denominator of all terms by b.
(ab)/b + 1/b = (ab+1)/b
