1/18_1/17
4/10_6/10
28/100_34/100

Answer 1

2/7 y 4/7;

(2/7+4/7) :2= 6/7• 1/2= 6/14= 3/7.



1/6 y 1/9;

(1/6+1/9):2= ( (1•3)/(6•3)+ (1•2)/(9•2) )• 1/2= (3/18+ 2/18)• 1/2= 5/18• 1/2= 5/36



1/18 y 1/17;

(1/18+ 1/17): 1/2= ( (1•17)/(18•17)+ (1•18)/(17•18) )• 1/2= ( 17/306+ 18/306)• 1/2= 35/306



4/10 y 6/10

(4/10+ 6/10):2= 10/10• 1/2= 1• 1/2= 1/2=0,5



28/100 y 34/100

(28/100+ 34/100):2= 62/100• 1/2= 31/100• 1/1= 31/100= 0,31
