1/2 - 1 1/3

Question

How do I solve this 

Answer 1

1/2-1 1/3 = 

turn into improper fraction

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

then make common denominator to substract

(1/2)*(3/3)-(4/3)*(2/2)=

3/6-8/6=-5/6

Answer 2

1/2 -1/3 =

 

 make the common denominator, so you can subtract.

 

   3/6  - 2 /6 = 1/6

Answer 3

1/2 - (1 1/3)

 

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

 

= 1/2 - 1 - 1/3

 

= 1/2 - 2/2 - 1/3

 

= (1 - 2)/2 - 1/3

 

= -1/2 - 1/3

 

= -1*3/(2*3) - 1*2/(3*2)

 

= -3/6 - 2/6

 

= (-3 - 2)/6

 

= -5/6
