Answer 1

Răspuns:

Explicație pas cu pas:

a) 1/8+(1/8)·4=1/8+4/8=5/8

b) 1/6+1/6:1/3= 1/6+(1/6)·3/1= 1/6+(1·3/6)=1/6+3/6=4/6=2/3

c) 4/9+3/10:(6/10)= 4/9+3/10·(10/6)= 4/9+(3·10)/(10·6)=4/9+3/6=4/9+1/2=(8+9)/18= 17/18

d) 1 1/3·2 1/2+6=(4/3)·(5/2)+6=(4·5)/(3·2)+6= (2·5)/3 +6= 10/3+18/3= 28/3

e) 2 1/7·1 1/5-(1/21):(1/3)=(15/7)·(6/5)-(1/21)·(3/1)= (15·6)/(7·5)-(1·3)/(21·1)=(3·6)/7-(1/7)=18/7-1/7=17/7

f) 5/6:(1/3+1/2:1/3)= 5/6:[1/3+(1/2)·(3/1)]= 5/6:[1/3+(1·3)/(2·1)]= 5/6:(1/3+3/2)= 5/6:(2+9)/6=5/6:11/6= 5/6·(6/11)=(5·6)/(6·11)=5/11
