rjkz [21]
One cat has four paws, so there are 120/4=30 cats.  If a "set" of cats is two uncool cats and three cool cats, there are five cats in a set, so there are 30/5=6 sets.  Since each of the six sets contains three cool cats, there are 18 cool cats in the family.

How do you identify the opposite and the absolute value of a rational number
Sergeeva-Olga [200]

Rational numbers are the numbers that can be written as the fraction of two integers and absolute value is the distance a number is away from 0. If we look at a number line, the absolute value is the distance any number on the number line is away from 0. Distance is always positive, so our absolute value is always 0.

   =    100 of them .

The number of possibilities that will match your age  =  only 1 .

Probability that the last 2 digits match your age = 1/100  =  0.01  =  1 % .
