Viết phân số thích hợp vào chỗ trống: 17/15 - .../.... = 8/15

a) \[\frac{{17}}{{15}} - \frac{9}{{15}} = \frac{8}{{15}}\]

c) \[\frac{{44}}{{19}} - \frac{{15}}{{19}} = \frac{{29}}{{19}}\]

b) \[\frac{{27}}{{36}} - \frac{{16}}{{36}} = \frac{{11}}{{36}}\]

d) \[\frac{{42}}{{37}} - \frac{{33}}{{37}} = \frac{9}{{37}}\]
