Okay, here we have this:
Considering that to convert from decimal to percent is needed just multiply the decimal value by 100, we obtain the following:
A) Convert 1.45 to a percent: 1.45*100=145%
B) Convert 0.08 to a percent: 0.08*100=8%
And to convert from a percentage to a decimal it is necessary to divide the number by 100:
C) Convert 47% to a decimal: 47/100=0.47.
D) Convert 4% to a decimal: 4/100=0.04.
