Prosze z dzialaniami :)

Answer 1

1. 4,67-(3 i 5/6- 1/3)=4,67-(3 i 5/6- 2/6)=4,67- 3 3/6= 4 67/100 - 3 50/100 = 1 17/100
2. 2,8+1 i 1/3x0,9=2 4/5 +1 1/3 x 9/10 = 2 4/5 + 1 1/5 = 4
3. 3,6:3/5-1 i 1/5= 3 3/5 :3/5 - 1 1/5 = 6 - 1 1/5 = 5 5/5 - 1 1/5 = 4 4/5
4. 0,2 do potegi drugiej x(1,6-2/5)= 1/5 x1/5 x ( 1 3/5 - 2/5) = 1/5 x1/5 x 1 1/5 =
=1/10 x 1 1/5= 3/25
5. 2/8x1 i 1/4-2/3x0,75= 1/4 x 1 1/4 - 2/3 x 3/4 = 5/16 - 1/2 = 5/16 - 8/16 = -3/16
6.(4,5-1,1)x2x3/4-1 = 3,4 x 2 x 3/4 - 1 = 6,8 x 3/4 - 1 = 6 4/5 x 3/4 - 1 = 5 1/10 - 1 =
=4 1/10
