**math question. **

are all whole numbers real numbers?

**Math.. 3rd time posting /: HELP PLEASE!**

Okay.

**Math.. 3rd time posting /: HELP PLEASE!**

All the whole numbers are rational because they can be written as a fraction, and irrational are the ones that can't be written as fractions. I understand that part.

**Math.. 3rd time posting /: HELP PLEASE!**

I don't understand how to do it, that's the thing I know that 8 is a whole number, and that the square root of four is 2, and that's a whole number, and the aquare root of 49 is 7, that's a whole number too, and -3 is an interger.

**Math.. 3rd time posting /: HELP PLEASE!**

Tell whether each number is a real number, rational number, irrational, interger, or whole number, and then order then from least to greatest. ( Square root sign) 49, 8, -( square root sign) 4, and -3.

**Math, ( Help please?)!**
