Question

Please help me ASAP!!!
What is − 9 over 20 as a decimal and as a percent?

Decimal:
Percent: %

Answer 1

9/20 

A percentage is the same as showing a number over 100 and if we multiply 20 by 5 we get 100.  So if we multiply 9 by 5 we get 45, giving us 45/100 which can be shown as 45%.

As a decimal, well if we say 100% equals 1.0, then 45% equals 0.45
