Answer 1

Respuesta:

ESPERO QUE TE SIRVA

Explicación paso a paso:

(7/9)+(-4/15)  

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

(-15/8)+(-11/12)=  

$-\frac{15}{8} -\frac{11}{12} =\frac{-45-22}{34} =-\frac{67}{24}$

25+(-11/4)=

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

17/24-5/12=

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

18/5-14=

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

Answer 2

Respuesta:

(7/9) +(-4/15)

7/9= 0,7

(-4)/35= -0,2

(-0,2) + 0,7 = 0.5

(-15/8)+(-11/12)

(-15)/8 = -1.875

(-11)/12 = -0.9

(-1.875) + (-0,9)= -1875.9

25+(-11/4)

(-11)/4 = -2.75

(-2.75) + 25 = 22.25

18/5 - 14

18/5 = 3,6

14 - 3,6 = 10.4
