Question

me explican esto?? Ejercicio 6

Answer 1

a) 12e+3e-16e-(-20e) = 12e+3e-16e+20e=35e-16e=19e
b) 1/4z-1/8z+1/5z=  1/4z=2/8z   
    2/8z-1/8z= 1/8z + 1/5z=       1/8z * 5/5= 5/40z     1/5z * 8/8= 8/40z
    5/40z + 8/40z = 13/40z
c)  0.6g - 3.4g -(-4.4g) + 1.1g = 0.6g - 3.4g + 4.4g + 1.1g = 6.1g - 3.4g= 2.7g

d) 1/2x - 6x + 1/4x -(-1/6x)  ;   1/2x= 2/4x       -6x * 4/4 = -24x/4
     2/4x -24x/4+ 1/4x +1/6x  = (2-24+1)/4x + 1/6x  = -21x/4 + 1/6x

     Convirtiendo en doceavos.
     -21x/4 x 3/3= -63/12             1/6x * 2/2= 2/12x
      -63x/12 + 2x/12= -61x/12 =
