Question

2/3 : [5 : (1/2 + 1) – 3(1/2-1/4) ]

Answer 1

→2/3 : [5 :(2/4 + 1/1) - 3(1/2 - 1/4)] =

2/3 : [ 5 :(2/4 + 4/4) - 3( 2/4 - 1/4)] =

2/3 : [ 5 :(6/4) - 3( 1/4)] =

2/3 : [ 5 * 4/6 - 3/4] =

2/3 : [ 20/6 - 3/4] = Simplificas 20/6 = 10/3

2/3 : [ 10/3 - 3/4 ] =

2/3 : [40/12 - 9/12] =

2/3 : [31/12]

2/3 * 12/31 =

(2 * 12) /(3 * 31) = Simplificas el 3

(2 * 4)/31 =

8/31
