Here's a way that will work for any terminating decimal.
Write that as a number over 1.
4.5

1
Now you want to move the decimal point to the right one place, but you have to do that as well in the denominator.
45

10
Now you can reduce the fraction. Both the numerator and denominator have a common factor of 5, so divide both by 5.
9

2
You can't reduce any further, so that is the answer.
4.5 = 9/2

From Mike G: 4.5 = 45/10 = 9/2

You can multiply ANY number by (1)
(10/10) = 1
4.5 (10/10) = 45/10
now reduce (remove factors of (1):
45/10 = (5/5) 9/2
so
9/2
====
OR another example, 0.005
0.005 (1000/1000) = 5/1000
This method works for any (nonrepeating) decimal.

From Captain Matticus, LandPiratesInc: 4.5 = x
10 * 4.5 = 10 * x
45 = 10x
45/10 = x

4.5 = x
10 * 4.5 = 10 * x
45 = 10x
45/10 = x
4.5 = x
45/10 = x
4.5 = 45/10
45/10 =>
(5 * 9) / (5 * 2) =>
9/2

4.5 with ".5" means it is some odd number of halves
4.5 = x/2
x = 2 * 4.5 = 9
4.5 = 9/2 as an improper fraction

The smallest decimal position is tenths (for the 5).
So we have 45 tenths.
45/10 . . . . . . . . cancel 5's
= 9/2

Start with 4.5 over 100, and find the least common deniminator between the two numbers. it would be 9/200, not 9/2. To get the decimaal to a whole number, it must be multiplied by 2 (4.5x2=9). But then, the denominator must also be multiplied by 2 (100x 2 =200). 4.5/100 = 9/200.

From sepia: 4.5
= 4 1/2
= 9/2

Reimagine your number as a fraction: 4.5/1
What would it take to make that a clean fraction? Aha! 4.5 is half of 9! To get there you'd double the numerator but you'll also have to double the denominator to match. So,
"Multiply by 1": 4.5 / 1 x 2 / 2 = 9 / 2
Okay, we got that out of the way. Now see if you can do the original problem without the calculator. :)

From Never Polled: 4.5/1 = 9/2 9 divided by 2 equals 4.5
