Question

Do 0.3 and 3.0 have the same value ? explain

Answer 1

No, 0.3 is a decimal and 3.0 is a whole number

Answer 2

Nope they do not have the same value let me show you why.
0.3 as a percent is 30% not that much right? well...
3.0 as a percent is 300% now thats alot.
lets look at these two as fractions
                  30
0.3    =     -------
                 100
               
                 300
3.0    =     -------
                 100
thats 3 times more than 100

and lastly 0.3<3.0 or in other words
0.3 is less than 3.0
hope this helps you:)
