Điền số thích hợp vào chỗ chấm

a) \[\frac{7}{6} + \frac{{...}}{6} = \frac{{11}}{6}\] b) \[\frac{{23}}{{15}} - \frac{{...}}{{15}} = \frac{8}{{15}}\] c) \[\frac{{...}}{{20}} - \frac{{11}}{{20}} = \frac{9}{{20}}\] d) \[\frac{{19}}{{17}} - \frac{{...}}{{17}} = \frac{8}{{17}}\]

e) \[\frac{{...}}{{20}} + \frac{9}{{20}} = \frac{{16}}{{20}}\] f) \[\frac{{...}}{{55}} + \frac{{29}}{{55}} = \frac{{48}}{{55}}\] g) \[\frac{{35}}{{19}} - \frac{{...}}{{19}} = \frac{{21}}{{19}}\] h) \[\frac{{49}}{{12}} - \frac{{...}}{{12}} = \frac{{35}}{{12}}\]
