Wykonaj obliczenia a)3*(1/3+14) b) (2-1/3):(1/2+1/3) c) (2 i 2/7-1/5)*5+4/7 d)
(1/2+2/3):(2/3+1/2) e) (1/2+2/3):2/3+1/2 f) 1/2+2/3:2/3+1/2

Answer 1

a)1+42=43

b) (1 i 2/3) : (3/6+2/6)= 1 i 4/6 : 5/6 = 10/6 : 5/6 = 2

c) (2 i 10/35- 7/35) *5+ 4/ =2 i 3/35*5 + 4/7 =73/35*5+ 4/7= 73/7 + 4/7 = 77/7 =11

d) ( 3/6 + 4/6 ): ( 4/6 + 3/6 )= 7/7 : 7/7 = 1

e) ( 3/6 + 4/6) : 4/6 + 3/6 = 7/6: 4/6 + 3/6 = 7/6*6/4  + 3/6 = 7/4 + 3/6= 42/24 + 12/24= 54/24 = 2 i 6/24= 2 i 1/4

f) 1/2 + 2/3 * 3/2+1/2= 1/2+1+1/2=1 i 2/2 = 2
