Question 2
Fill in the blanks
$$\frac {1}{4} - ....... = \frac {-1}{36}$$
$$ ...... - \frac {1}{18 } = \frac {23}{72}$$
$$\frac {2}{7} - \frac {2}{15 } = .........$$
$$\frac {4}{15} - \frac {1}{13 } = ........$$
$$\frac {1}{12} + \frac {1}{8 } = ........ $$
$$\frac {1}{16} + ....... = \frac {5}{16}$$
$$\frac {1}{4} - \frac {5}{16 } = ......$$
$$\frac {2}{7} - ........ = \frac {-1}{119}$$
$$........ - \frac { 1}{5 } = \frac {3}{85}$$
