Question

Oblicz :

2 i 3/7 * 12 =

2 i 3/5 : 1 i 3/10 =

2 : 1/3 =

3 i 1/8 : 1 i 1/4 =

(-2 i 3/4) + (1 i 1/3) =

-5 * (-12-3) - (-23) =

-2 * (-4-12) + (-3+2) =

-4 i 1/3 + (-3 i 2/5) =

8 i 1/3 + (-10 i 2/5) =

Answer 1

2 3/7*12/1=17/7*12/1=204/7=23 1/7

 

2 3/5÷1 3/10=13/5÷13/10=13/5*10/13=130/65=2

 

2÷1/3=2/1÷1/3=1/2*1/3=1/6

 

3 1/8÷1 1/4=25/8÷5/4=25/8*4/5=100/40=2,5

 

(-2 3/4)+1 1/3=(-2 9/12 )+1 4/12= (-1 5/12)

 

-5*(-12-3)-(23)= -5*(-15)-23=75-23=52

 

 8 1/3 + (-10 2/5) =8 5/15+(-10 6/15)=-2 1/15

 

 -4  1/3 + (-3  2/5) =-4 5/15+(-3 6/15)= -7 11/15
