Ohh yeaaaa
To show that a number is a rational number, we need to express it as a fraction of two integers.
The number 2.4 can be written as a fraction by considering the place value of each digit. The digit '2' is in the units place, the digit '4' is in the tenths place (10^-1), and there are no other digits after the tenths place.
To convert 2.4 into a fraction, we can use the fact that 1.0 is equal to 1. So, we can write 2.4 as 2 + 0.4.
The digit '4' in the tenths place can be expressed as 4/10 or 2/5 in its simplest form. Hence, 0.4 is equal to 4/10 or 2/5.
Now, adding the whole number 2 and the fraction 2/5, we get 2 + 2/5 = (2 * 5 + 2) / 5 = 12/5.
Therefore, 2.4 can be written as the fraction 12/5, which shows that it is a rational number.
