1. Is
130
rational or irrational? Where would
130
be located
on a number line? Explain your reasoning.
130
is a rational number because 130 is even. All
rational numbers are even and irrational numbers are
odd when the numbers are under the square root sign.
The square root sign is the opposite of squaring a
number. Squaring a number is the same as raising it
to the 2nd power. So, to find the value of a number
under the square root sign, you divide it by 2. So,
130÷2 is 65. The answer is 65.
