Question

Resuelve las siguientes sustracciónes 8/9 -10/3= 3/5 - 1/3= 8/15 - (-5/12)= 7/8 - 9/4= 3/4 - (-7/3)= - 7/8 - 1/2=​

Answer 1

Explicación paso a paso:

Resuelve las siguientes sustracciones:

$\frac{8}{9} - \frac{10}{3}=\frac{(8)(1) - (10)(3) }{9} =\frac{8-30}{9} =\frac{-22}{9} \\\\\frac{3}{5} - \frac{1}{3}=\frac{(3)(3) - (1)(5) }{15} =\frac{9-5}{15} =\frac{4}{15} \\\\\frac{8}{15} - \frac{-5}{12}=\frac{(8)(4) - (-5)(5) }{60} =\frac{32+25}{60} =\frac{57}{60} =\frac{19}{20} \\\\\frac{7}{8} - \frac{9}{4}=\frac{(7)(1) - (9)(2) }{8} =\frac{7-18}{8} =\frac{-11}{8}\\\\\frac{3}{4} - \frac{-7}{3}=\frac{(3)(3) - (-7)(4) }{12} =\frac{9+28}{12} =\frac{37}{12}$

$\frac{-7}{8} - \frac{1}{2}=\frac{(-7)(1) - (1)(4) }{8} =\frac{-7-4}{8} =\frac{-11}{8}$
