EXPLANATION
If we do not have a fraction calculator, we can aaply the following relationship in order to get the decimal form:
If the number is for instance 7/100, then:
Consider the numerator
Then mark the decimal point after one place or two places or three places from right towards left if the given fraction's denominator is 10, 100 or 1000, respectively.
So, in this case 7/100 should be represented as follows:
7/100 = 0.07 [The denominator has two zeros]
But if we have 77/100
The decimal number is 77/100 = 0.77 [because the numerator has two numbers]
If we have the number 999/1000 the decimal number is 0.999
