Answer:
- nine twentieths, or forty-five hundredths
- 0.45
- 45%
Step-by-step explanation:
The fraction 9/20 can be represented using a diagram in which nine of twenty objects are shaded. If each of the objects in the diagram is further subdivided into 5 objects, then a total of 5×9 = 45 out of 5×20 = 100 will be shaded.
That is, ...
9/20 = 45/100 = 0.45 = 45%
__
Forty-five out of one hundred is "forty-five hundredths." That is the pronunciation of the decimal fraction 0.45.
We note that the symbol % is fully equivalent to /100, and can be considered to be a shorthand way to write /100. That is ...
45/100 = 45%
__
9/20 = 45/100 = 45% = forty-five hundredths = 0.45

Additional comment
To give a little context, the % symbol is short for /100 (percent or hundredths), and the ‰ symbol is short for /1000 (mils or thousandths).
