are decimal fractions, whose numerators are 426340, 452806, 20010, and 540000, and whose common denominator is 10000. By (112) their sum is
| 426340 + 452806 + 20010 + 540000 | , which is | 1439156 |
|---|---|---|
| 10000 | 10000 |
or 143·9156. The simplest way of doing this is as follows: write the decimals down under one another, so that the decimal points may fall under one another, thus:
- 42·634
- 45·2806
- 2·001
- 54
- 143·9156
Add the different columns together as in common addition, and place the decimal point under the other decimal points.
