Question

Cuanto es 3 2/4 + 6 4/8 + 2 3/4 y también 26 3/9 - 14 2/3

Answer 1

 3 2/4 + 6 4/8 + 2 3/4

 3 2/4 = (4*3+2)/4 =14/4 
 6 4/8 = (8*6 +4)/8 = 52/8  = 26/4
 2 3/4 =  (2*4 +3)/4 =  11/4

 3 2/4 + 6 4/8 + 2 3/4
14/4 + 26/4 + 11/4 = (14+26+11)/4 = 51 /4

26 3/9 - 14 2/3

26 3/9 =  26  1/3  = (26*3 +1)/3 = 79/3
14 2/3 = (14*3+2)/3 = 44/3

26 3/9 - 14 2/3
79/3-44/3 = 35/3
