how do you rewrite rational numbers -0.56, -2.3,2.11, I do know where to start I'm a mom trying to help my son with his homework

No problem, I'll be glad to help you and your son with rewriting the given rational numbers.

To rewrite rational numbers, we need to express them as fractions in the form of p/q, where p and q are integers (whole numbers) and q is not equal to zero.

Let's start with the first number, -0.56. To rewrite it as a fraction, we need to determine the place value of the last digit after the decimal point. In this case, the last digit is 6, which is in the hundredths place.

Since there are two decimal places, we can express -0.56 as a fraction by placing the number over 100 (because there are two decimal places).

So, -0.56 can be rewritten as -56/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which in this case is 4.

Dividing both -56 and 100 by 4, we get -14/25. Therefore, -0.56 can also be written as -14/25.

Now, let's move on to the second number, -2.3. The digit 3 is in the tenths place. Therefore, we represent it as -2 3/10. This is already in fraction form.

Lastly, for the third number, 2.11, the digits 1 and 1 are in the tenths and hundredths places, respectively. So, we represent it as 2 11/100.

To summarize the rewritten rational numbers:

-0.56 = -14/25
-2.3 = -2 3/10
2.11 = 2 11/100
