Question

A)3,6+2/3=

B)4(1/8)-1,11=

C)2,75-+2/7=

D)0,125-1/9=

E)3(1/3)-3,3=

F)1(1/5)-0,O9=

Answer 1

A)3,6+2/3= 3.6 + 0.(6) = 4.2(6)

B)4(1/8)-1,11= = 4.125 - 1.11 = 3.015

C)2,75+2/7= 2 i 3/4 + 2/7 = 2 i 21/28 + 8/27 = 3 i 1/27

D)0,125-1/9= 1/8 - 1/9 = 9/72 - 8/72 = 1/72

E)3(1/3)-3,3= 3 i 1/3 - 33/10 = 10/3 - 33/10 = 100/30 - 99/30 = 1/30

F)1(1/5)-0,O9= 1.2 - 0.09 = 1.11
