N.B. The student should write this table himself, and then proceed to make similar tables from the following exercises.
EXERCISES.
Reduce the following fractions into a series of numbers and more simple fractions:
| 31415926 | , | 31415926 | ,&c. |
| 10 | 100 | ||
| 2700031 | , | 2700031 | ,&c. |

| 3331303 | , | 3331303 | ,&c. |
| 1000 | 10000 |
133. If, in this table, and others made in the same manner, you look at those fractions which contain a whole number, you will see that they may be made thus: Mark off, from the right hand of the numerator, as many figures as there are ciphers in the denominator by a point, or any other convenient mark.
| This will give | 14732·6 | when the fraction is | 147326 |
| 10 | |||
| 1473·26 | 147326 | ||
| 100 | |||
| 147·326 | 147326 | ||

The figures on the left of the point by themselves make the whole number which the fraction contains. Of those on its right, the first is the numerator of the fraction whose denominator is 10, the second of that whose denominator is 100, and so on. We now come to those fractions which do not contain a whole number.
134. The first of these is ¹⁴⁷³²⁶/₁₀₀₀₀₀₀ which the number of ciphers in the denominator is the same as the number of figures in the numerator. If we still follow the same rule, and mark off all the figures, by placing the point before them all, thus, ·147326, the observation in (133) still holds good; for, on looking at ¹⁴⁷³²⁶/₁₀₀₀₀₀₀ in the table, we find it is
