Just write a few 9s, the non-cyclic part has a few digits followed by a few zeros, and the numerator is the significant number of the whole decimal part minus the non-cyclic part.; loop) = 1 again 57 99;cycle) = (42-4) 90 = 38 90;circulation) = 2 and (353-3) 990 = 2 and 350 990;Loop)=9 and 5 Cycle)=10 99;loop) = 10 99, the same size.

Anonymous users2024-02-14No, write them as two decimal parts with the same digit, and then see if the number on each digit is the same, because the ratio of the size is the number on the digit who is bigger and who is smaller, and if the number on each digit is the same, then the number is the same. So let's look at the first place, the cycle of 01 is written as a number with six decimal places, and then the cycle of 10 is written as a number with six decimal places, that is, we can see that the number on each digit of these two numbers is the same, and will continue to be the same, so these two numbers are equal.

Anonymous users2024-02-12Summary. The answer is 73 99
What is the fraction of dividing the infinite loop into fractions.
The answer is 73 99
When there are several digits in the cyclic node during the cyclic decimal transformation, the numerator is the cyclic node, and the denominator has several 9s

Anonymous users2024-02-10Solution: Is it necessary to infinitely loop the decimal number99……99……"Convert into fractions? If yes, share a solution and use an equation to solve it.
Take " as an example, let , then the two sides are multiplied by 10, there is 10x=, x=1 9, that is. The others follow this and follow the same rule, in order of 9.
FYI.

Anonymous users2024-02-09An infinite cyclic decimal fraction is actually the sum of the infinite terms of an equal proportional series, which is an application of limit operations.
an(n→+∞=a1/(1-q)
Here the common ratio q must meet 0 |q|＜1
The cyclic decimal of = the first term a1=, the common ratio q=
So the cyclic decimal =
Similarly: the cyclic decimal = 2 9
Cyclic decimal = 3 9 = 1 3
Cyclic decimal = 4 9
Cyclic decimal = 5 9
Cyclic decimal = 6 9 = 2 3
Cyclic decimal = 7-9
Cyclic decimal = 8 9
Cyclic decimal = 9 9 = 1
The decimal part of a number starts from a certain digit, and the infinite decimal number of one or several numbers repeating in turn is called a cyclic decimal. Loop decimal will have loop knots (loop points). When two integers are divided, if the integer quotient is not obtained, there are two cases: >>>More
Infinite loop decimals.
A digit after the decimal point begins to repeat the decimal system of the previous digit or sections. >>>More
No, a cyclic decimal is a number after the decimal point that looks like something about the same, and it is infinite.
The decimal that starts the cycle from the first decimal place after the decimal point is called a pure cyclic decimal The method of converting a pure cyclic decimal into a fraction is: the numerator is a number composed of the numbers of a cyclic node; The denominator is 9, and the number of 9 is equal to the number of digits of a cyclic section >>>More
Yes, you need to make it into a fraction first.
Infinite cyclic decimal numbers belong to rational numbers, which can be expressed in the form of fractions, and fractions can be directly added and subtracted, so infinite cyclic decimals can be directly added and subtracted. >>>More
