Answer 1

Explicación paso a paso:

solucion:

a)$\frac{8}{9}  -\frac{3}{10} =\frac{80-27}{90}=\frac{53}{90}$

b)$-\frac{3}{5} -\frac{1}{3} =\frac{-9-5}{15} =\frac{-14}{15}$

c)$\frac{8}{12} -(\frac{5}{12} )=\frac{8}{12} -\frac{5}{12} =\frac{8-5}{12} =\frac{3}{12}$

d)$(-\frac{4}{9} )-(\frac{5}{18} )=-\frac{4}{9} -\frac{5}{18} =\frac{-72-45}{18} =\frac{117}{18}$

e)$(\frac{3}{4} -(-\frac{7}{3} )=\frac{3}{4} +\frac{7}{3}=\frac{28+9}{12} =\frac{37}{12}$

f)$\frac{7}{2} -(-\frac{9}{4} )=\frac{7}{2} +\frac{9}{4} =\frac{28+18}{8} =\frac{46}{8}$
