When you have a fraction like the one you mentioned and want to turn it to a decimal figure, you have just to divide the first number by the second one. In this case it turns out to be 0.45. To explain more, you start by dividing the 20 and 20 into 9 there is no unswer so you have to put a point (.) Then the 9 is added by a 0 becoming a 90. Now 20 into 90. This time 20 x 4 = 80, so you have to put after the point (.) 4. From 90 you subtract 80 which leaves 10. Add a 0 which make it 100. Now divide again the 20 into 100, which comes 5. So the final answer is .45. You also keep in mind that whenever the second number of the fraction is bigger than the first one it has for sure to be with a point (.) If on the other hand the second one is smaller than the first like 32/20 than there surely have to begin with a whole number followed by a point (.) since 20 is smaller than 32. Got it?
You can easily do it with a calculator, even the cheapest. Make 9 divided by 20 and it will come the answer of .45.
This method is used on every fraction. The longest way is by the first part and the quickest and shortest is by the calculator which I recommend if you have many to do. Also you can rely on the calculator.

If you don't want to use a calculator, simply divide 9 by 20

No 20s go into 9 so 0 (9 goes over)
4 20s go into 90 (so 10 goes over)
5 20s go into 100 (terminates)

Hence 0.45

Lol can't beleive i just typed that

undergo in concepts that possibilities are out of one hundred. to alter it right into a decimal, flow the decimal factor of the share 2 areas to the left. to alter it right into a fragment, placed the share over a hundred and simplify. 345% = 345/a hundred decimal = 3.40 5 fraction = sixty 9/20 or 3 and 9/20 a hundred and ten% = a hundred and ten/a hundred decimal = a million.a million fraction = 11/10 or a million and a million/10 108% = 108/a hundred decimal = a million.08 fraction = 27/25 or a million and a pair of/25 230% = 230/a hundred decimal = 2.3 fraction = 23/10 or 2 and 3/10
