Question

Order these least to greatest 100%,1/100,0.001,1.1,10,10,000/100

Answer 1

For these, this best way to approach it is to change it all into one form of number, be it fraction, decimal an percentage. If we do, it turns to this:
100% = 1 or 1/1
1/100 = 1% or .01
0.001 = 1/1000 or 0.1%
1.1     = 110% or 11/10
10      = 1000% or 10/1
10,000/100 = 100 or 10000%

If you work with fractions, you will additionally need to change the denominators to become the same....

In the end, here is you order from least, to greatest:
0.001, 1/100, 100%, 1.1, 10, 10,000/100
