Is -49 rational or irrational
A number is rational when it can be expressed as a fraction of integers.
For example, 24 is rational because
24=24/1=48/2...
-3 is rational
because
-3 = -6/2 = -3/1 ....
So see if you can figure out if -49 is rational.
To determine whether -49 is rational or irrational, we first need to understand what rational and irrational numbers are.
A rational number is any number that can be expressed as a fraction (ratio) of two integers, where the denominator is not zero. For example, 3/4, -2/5, and 7 are all rational numbers because they can be written as fractions.
On the other hand, irrational numbers are numbers that cannot be expressed as a fraction of two integers. They are non-repeating and non-terminating decimals. Examples of irrational numbers include pi (π), the square root of 2 (√2), and e.
Now, let's consider -49. Since -49 can be expressed as -49/1, we can see that it is a fraction and therefore a rational number. Therefore, -49 is rational.
