Answer 1

34-4*5=34-20=14

20:2do p2 = 20:4=5

24;(3*4)=24;12=2

22-(5+6)= 22-11=11

2x(20+14;2)=2x(20+7)=2x27=54

(25-(3+8)x8=(25-11)x8=14x8=112?

 

3,2;(0,8-0,5)=3,2;0,3=10,6                                               1/2=5/10=0,5

Answer 2

a)34-4*5=34-20=14

b)20:2 do potęgi drugiej=20:4=5

c)24:(3*4)=24:12=2

d)22-(5+6)=22-11=11

e)2*(20+14:2)=2*(20+7)=2*27=54

f)(25-(3+8)*8=(25-11)*8=14*8=112

 

zad 4/35

b)3,2:(0,8-1/2)=3,2:0,3=10,6

c)2/3 * (1/2-1/6)=2/3 * 1/6=1/9

d)4,8+1/3*(1,2-0,6)=4,8+1/3*0,6=4,8+0,2=5

e)(1-7/9)*(5,2-0,7)=2/9*4,5=1

f)123:10+0,2*6,1=12,3+1,22=13,52

g)(6,5-4,7):(4-2 1/5)=1,8:1 4/5=1,8:1,8=1

h)(1,5-1 1/3)*2 2/5-0,1=1/6*2,3=23/60
