To express a percentage as decimal numbers you have to make the following convertion:
Consider that 100% is equal to 1, use cross multiplication to convert 7%:
100%____1
7%____x
[tex]x=\frac{7\cdot1}{100}=\frac{7}{100}=0.07[/tex]So, remember, to transform any percentage in decimal numbers, just divide it by 100.
