00:00:00.000 --> 00:00:03.471
Here is the problem: 7 over 2 plus 1 over 9.

2
00:00:03.921 --> 00:00:07.845
Exact arithmetic with fractions (results kept in lowest terms).

3
00:00:08.645 --> 00:00:14.833
Rewrite both fractions with the least common denominator. The LCD of 2 and 9 is 18.

4
00:00:15.283 --> 00:00:17.524
Add the numerators and keep the denominator.

5
00:00:17.974 --> 00:00:20.122
Final answer in lowest terms.

6
00:00:20.922 --> 00:00:23.604
So the answer is 65 over 18.

7
00:00:24.054 --> 00:00:37.011
Fractions are combined over a common denominator for addition and subtraction, multiplied straight across, and divided by multiplying by the reciprocal. The result is reduced by the greatest common factor.

8
00:00:37.811 --> 00:00:44.115
Decimal check: 65 over 18 approximately 3.611111111.

9
00:00:44.565 --> 00:00:47.967
