Me and fast : ( find the rational form of the decimal number. 1. 0.55 2. 0.36 3. 0.128 4. 0.0545454 5. 0.04666666type answer below and explain answer.

9514 1404 393

Step-by-step explanation:

It is helpful to know the decimal equivalents of 1/9 and 1/11:

  1/9 = 0.1111...

  1/11 = 0.09090909...

__

1. 0.55 = 55/100 = 11/20

2. 0.36 = 36/100 = 9/25

3. 0.128 = 128/1000 = 16/125

4. 0.0545454... = (1/10)(6×1//11) = 6/110 = 3/55

5. 0.046666... = 4/100 + (1/100)6×1/9 = 1/25 + 1/150 = (6+1)/150 = 7/150

In 4 and 5, we recognize that ...

  0.545454... = 6/11 has been divided by 10 to get 0.0545454...

  0.6666... = 6/9 = 2/3 has been divided by 100 to get 0.006666...

the solution is 12x-6y

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
