4. 14,2

5.0,15 

6.0,67

7.16,20 

8. 2,789

Answer 2

(1/2)*0,36= (1/2)* (36/100) = (18/100) =0,18

1,8*(2/3)=(18/10)*(2/3)=(9/5)

1(4/7) * 0,042 = (11/7)*(42/1000)=(66/1000)=0,066

2,13 :(1/5) = 2(13/100)*(5/1)=(213/100)*(5/1)=(213/20)=10(13/20)=10,65

0,72 : 1(2/7) = (72/100)*(7/9)=(14/25)

2(2/5):0,024 =
(12/5)*(1000/24)=(1/100)=0,01

5(1/6) :(5/26) = (31/6)*(26/5)=(403/15)=26(13/15)

4(6/8)*3(1/8):2(4/7)=(38/8)*(25/8)*(7/18)=5(445/576)
