Điền số hoặc phân số thích hợp vào chỗ trống. a) 3/ 5 + . . . . . . = 13 /10

a) \(\frac{3}{5} + \frac{7}{{10}} = \frac{{13}}{{10}}\)   

b) \(\frac{{13}}{8} - \frac{3}{8} = \frac{5}{4}\)             

c) \(\frac{5}{6} \times \frac{4}{3} = \frac{{10}}{9}\)        

d) \(\frac{5}{{16}}:\frac{5}{8} = \frac{1}{2}\)

e) \(\frac{{41}}{{56}} + \frac{1}{8} = \frac{6}{7}\)             

f) \(\frac{{49}}{{18}} - \frac{2}{9} = \frac{5}{2}\)             

g) \(\frac{{135}}{{32}} \times \frac{8}{{15}} = \frac{9}{4}\)                   

h) \(\frac{6}{{13}}:\frac{{15}}{{13}} = \frac{2}{5}\)
