Question

Find two rational numbers whose absolute value is 1/5.

Answer 1

Hi,

Definition:

Absolute value of an integer is the

numerical value of the integer

regardless of its sign.

If ' x ' is an integer then its absolute

value is denoted by l x l and is

defined as

i) l x l = x if x is positive

ii) l x l = - x , if x is negative

iii) l x l = 0 , if x is zero

According to the problem,

Two rational numbers 1 ) 16/ 80

2) - 8 / 40 its absolute values are 1/5,

1 ) l 16 / 80 l = 16/ 80 = 1/ 5

2) l - 8 / 40 l = - ( - 8 / 40 ) = 8/ 40 = 1/5

I hope this will useful to you.
