Question

efetue as divisoes:
A) (1/4 +1///2) : (3/2 +3)=
b) ( 1/2 - 1/6 ) : ( 1/3 - 1/4 )=

Answer 1

a) (1/4+1/2) : (3/2 + 3)=
1/4+1/2= 1/4+2/4= 3/4

3/2 +3= 3/2 +6/2= 9/2

3/4 : 9/2= 3/4 . 2/9= 6/36= 3/18= 1/6

b) (1/2 - 1/6) : (1/3 - 1/4)=
1/2-1/6= 3/6-1/6= 2/6= 1/3

1/3 -1/4= 4/12 -3/12= 1/12

1/3 : 1/12= 1/3 .12/1= 12/3= 4
