Question

1/12+1/13? 1/12-1/13?

Answer 1

Ответ:

$\frac{1}{12} + \frac{1}{13} = \frac{13 + 12}{156} = \frac{25}{156}$

$\frac{1}{13} - \frac{1}{13} = \frac{13 - 12}{156} = \frac{1}{156}$

Answer 2

To add 1/12 and 1/13, you need to find a common denominator, which in this case is 156. Then, you can add the fractions:

(1/12) + (1/13) = (13/156) + (12/156) = (13 + 12) / 156 = 25/156

To subtract 1/12 from 1/13, you also need a common denominator of 156:

(1/13) - (1/12) = (12/156) - (13/156) = (12 - 13) / 156 = -1/156
