Thực hiện phép tính:

a) (\(\frac{3}{8}\)+ \(\frac{-3}{4}\)+ \(\frac{7}{12}\)) : \(\frac{5}{6}\)+ \(\frac{1}{2}\)

b) \(\frac{1}{2}\)+ \(\frac{3}{4}\)- (\(\frac{3}{4}\)- \(\frac{4}{5}\))

c) \(6\frac{5}{12}\): \(2\frac{3}{4}\)+ \(11\frac{1}{4}\). (\(\frac{1}{3}\)- \(\frac{1}{5}\))

d) (\(\frac{7}{8}\)- \(\frac{3}{4}\)) . \(1\frac{1}{3}\)- \(\frac{2}{7}\). (3,5)²

e) (\(\frac{3}{5}\)+ 0,415 - \(\frac{3}{200}\)) .\(2\frac{2}{3}\). 0,25

f) \(\frac{5}{16}\): 0,125 - (\(2\frac{1}{4}\)- 0,6) . \(\frac{10}{11}\)

g) 0,25 : (10,3 - 9,8) - \(\frac{3}{4}\)

h) \(1\frac{13}{15}\). 0,75 - (\(\frac{11}{20}\)+ 25%) : \(\frac{7}{3}\)

i) \(\frac{\left(\frac{1}{2}-0,75\right).\left(0,2-\frac{2}{5}\right)}{\frac{5}{9}-1\frac{1}{12}}\)

k) \(\frac{\frac{2}{3}+\frac{2}{7}-\frac{1}{14}}{-1-\frac{3}{7}+\frac{3}{28}}\)
