Question

1•1/3+1/6=
[2•1/3-(1/2)²] :5/6:

40%din 20
Va rog ajutorr

Answer 1

a) 1/3+1/6 amplificam pe 1/3 cu 2

2/6+1/6 = 3/6 = 1/2

b) [2/3-1/4]:5/6 amplificam pe 2/3 cu 4 si pe 1/4 cu 3

[8/12-3/12]:5/6 = 5/12*6/5 = 1/2

c) 40/100*20 = 2/5*20 = 2*4 = 8

Answer 2

1 × 1 / 3 + 1 / 6 =

1 / 3 + 1 / 6 =

2 / 6 + 1 / 6 =

3 / 6 = 1 / 2

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

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

( 8 / 12 - 3 / 12 ) : 5 / 6 =

5 / 12 : 5 / 6 =

5 / 12 × 6 / 5 =

30 / 60 = 1 / 2

40 % din 20 = 40 / 100 × 20 = 800 / 100 = 8
