To express a decimal number (with a finite decimal expression) in a fraction, you work like this: the numerator is the number without decimale separator (you simply pretend it's not there), while the denominator will be  , where n is the number of digits after the decimal separator.
, where n is the number of digits after the decimal separator.
So, in your case, the number without decimal separator is 53, and you have two digits after the decimal separator, so the fraction will be
 
 
which is irreducible.

Answer:
Step-by-step explanation:
I=PRT/100
I=5000*10*4=200,000/100

Answer:
The answer would be 0.8, 8 squares filled.
Step-by-step explanation:
This is because 0.4*2 is 0.8 and that out of a grid of 10 means that 8 cubes would be shaded.
