0.45 = 45/100. The greatest common factor of 45 and 100 is 5 and dividing both by 5 gives 9/20.
A decimal number is a way of representing a number in such a way that the place value of any digit is ten times that of the digit in the place to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So the decimal for 1720 is 1720 – exactly as in the question.
the simplest fraction is 2/5
15.45 is a decimal fraction and, being a decimal representation, it IS in its simplest form. The equivalent rational fraction is simplest form is 309/20.
0.12 is already a decimal equivalent to 3/25 as a fraction in its simplest form
2.58 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, being a decimal fraction, it is in its simplest decimal form. Its equivalent, in rational form, is 129/50.
The decimal 2.14560 can be simplified to the fraction 42912/20000 by removing the decimal point and reducing the fraction to its simplest form. The fraction is equivalent to 10728/5000 when further simplified. The decimal 2.1456 is equivalent to the fraction 2682/1250 when simplified. The fractions are not the same due to the additional zero in the first decimal number.
