WALT convert between decimals and percentages

Converting between decimals and percentages is easy when you know what to look for. 
Remember that 1.00 = 1 whole = 100% - these things are all the same. 
So 0.50 will be 50%, 0.30 = 30%, 0.10 is 10%. 

E.g. using different place value positions
12.87 = 1,287%
4.56 = 456% 
1.42 = 142%
0.56 = 56%
0.09 = 9%
0.005 = 0.5%

*Remember to check your place value*

Change these decimals into percentages (put it next to the decimal).
