Answers
SOLUTION
TO DETERMINE
The number of decimal places does the decimal expansion of terminates
EVALUATION
Here the given fraction is
Which can be simplified to
So the denominator = 10
Now 10 = 2 × 5
So the denominator of the fraction consists only 2 and 5 as prime factors
So the given fraction is terminating
Now the exponent of 2 = 1
The exponent of 5 = 1
Now the maximum value of the exponents = 1
So the given fraction terminates after one decimal place
More precisely = 0.7
