(7/9)+(-4/15) =
(-15/8)+(-11/12)=
25+(-11/4)=
17/24-5/12=
18/5-14

Answer 1

Respuesta:

Explicación paso a paso:

(7/9)+(-4/15)  mcm (45)

$\frac{7}{9} -\frac{4}{15} =\frac{35-12}{45} =\frac{23}{45}$

(-15/8)+(-11/12)=  mcm(24)

$-\frac{15}{8} -\frac{11}{12} =\frac{-45-22}{24} =-\frac{67}{24}$

25+(-11/4)=mcm(4)

$25 -\frac{11}{4} =\frac{100-11}{4} =\frac{89}{4}$

17/24-5/12= mcm(24)

$\frac{17}{24} -\frac{5}{12} =\frac{17-10}{24} =\frac{7}{24}$

18/5-14=mcm(5)

$\frac{18}{5} -14 =\frac{18-70}{5} =-\frac{52}{5}$
