Answer:
Infinite Decimals.
Rational numbers can be represented as a fraction.
Infinite decimals cannot be represented as fractions, therefore they are not rational.
To solve this problem, let us assign the variables. Let
us say that:
x = age of Tony = which also the age of his twin brother Evan
x + 4 = age of Josh (since tony is 4 years younger, then
josh must be 4 years older)
x – 2 = age of Cindy (since tony is 2 years older, then
cindy must be 2 years younger)
There are a total of 4 children, therefore:
x + x + x + 4 + x – 2 = 66
4 x + 2 = 66
4 x = 64
x = 16
Therefore Tony is 16 years old.
