Question

hola me ayudan a resolver estás 3 operaciones en fracciones? (5/2+1/3)×27+(1/7÷1/2) b (1/3×2/5) + (1/7÷1/14) c 0,5+ 1 1/3 - 1/12. desde ya gracias​

Answer 1

Explicación paso a paso:

a) 5/2+1/3)= 15+2/6= 17/6

(17/6) x 27+ 1/7 -1/2= 7-2/14= 5/14

17/6 x 27/1= 459/6

459/6-5/14=6426-30/84 = 6396/84= 3198/42= 1599/21=533/7= 76.14

b) 1/3 x 2/5= 2/15

1/7÷1/14= 14/7= 2/15+14/7= 210+14/105= 224/105= 32/15

c) 0.5+ 11./3- 1/12=

0.5 equivale a 1/2 entonces

1/2+11/3= 22+3/6= 25/6

25/6-1/12= 300-6/72= 294/72= 147/36= 49/12
