let x,y,z be 3 different + integers each less than 20 .what is

Question

smallest possible value of expression x-y/-z and plz explain me how to choose a number sir

Answer 1

The smallest value will occur when your numerator is positive and is large as possible and your denominator is negative and as small as possible

 

So in this case  the smallest possible positive integer less than 20 would be 1

 

so let z = 1

 

now we want the largest value for the numerator  so we want a large x and a small y

 

so let x = 19 and y = 2

 

then our result becomes

 

(x-y)/-z

 

(19-2)/-1

 

= -17  and that would be the smallest possible value

 

Hope this helps
