Write 9/11 as a decimal using long division will mark brainest these are so confusing

0.81 (repeated 81) (On paper, raw a straight line above the 8 and 1)

Step-by-step explanation:

To divide by long division to get a decimal number, you divide normally. For the decimals after "9", add some 0's. Follow the long division process, which you remember with DMS↓. (Divide, multiply, subtract, down).

This is the set up:

11 ∫9.0000

Here are the first few steps:

Divide: (11 goes into 9 "0" times. Write "0" in the answer place directly above the "9").

    0.

11 ∫9.0000

Multiply the last used digit in answer by 11. (0 X 11 = 0. Write the answer under "9").

    0.

11 ∫9.0000

    0

Subtract under the original division question. (9 - 0 = 9)

    0.

11 ∫9.0000

 -  0

    9

Down ↓. Bring down the next digit from the question.

    0.

11 ∫9.0000

 -  0 ↓

    9 0

Now start the process again.

Divide. (Divide 11 by 90. It goes in 8 times with remainders. Write "8" in the answer.)

    0.8

11 ∫9.0000

 -  0 ↓

    9 0

Multiply. (Multiply 8 and 11, write the product under 90.)

    0.8

11 ∫9.0000

 -  0 ↓

    9 0

    8 8

Multiply. (Subtract 88 from 90.)

    0.8

11 ∫9.0000

 -  0 ↓

    9 0

 -  8 8

        2

Repeat the process until you end up subtracting 0s, or until you get repeating decimals.

The final looks like this:

    0.8 181     Decimal is going to repeat.

11 ∫9.0000

 -  0 ↓

    9 0

 -  8 8 ↓

        2 0

     -   1 1 ↓

           9 0

       -   8 8 ↓

               2 0

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
