Answer 1

Respuesta:

1) 9/4 + (-12)/4 + (-10)/4

  9/4-12/4-10/4= -13/4  = -3.25 ___>fracción homogénea

2)  (-20)/9 -(-16)/9 + 7/9

  $-\frac{20}{9} +\frac{16}{9} +\frac{7}{9}=\frac{3}{9}=\frac{1}{3} =0.33333..$

3) 24/7 + 39/8

$\frac{27x8+38x7}{8x7} =\frac{482}{56} =\frac{241}{28} =8.607142857$

4) 47/6 + 57/9

   $\frac{47x9+57x6}{6x9} =\frac{765}{54} =\frac{85}{6}=14.16666667$

5)  94/28 - 37/5

  $\frac{94x5-28x37}{28x5}= \frac{-566}{140} = -\frac{283}{70}=-4.042857143$
