how do i divide 11 and 220

Question

11√220

 

Answer 1

I'm not sure if you're asking about division or square root. I'm going to assume square root.

 

In order to simplify a square root you need to break 220 into factors that are squares.

 

For example, 220 = 100 * 22.

 

Therefore 11√(220)

= 11√(100 * 22)

= 11 √100 * √22

= 11 * 10 * √22

= 110√22

 

22 has no factors that are squares, since it's 2 * 11. So we're done.

Answer 2

1. Start by asking how many times does 11 go into 22? The answer is 2. You place the 2 on top of the division sign and multiply it times the number in front of the division sign. 2 * 11 = 22.

 

2. Take that number and write it directly under the 22 that is underneath the division sign. Then subtract. 22 - 22 = 0.

 

3. Now ask yourself how many times does 11 go into 0? Zero. So you now write a 0 directly above the 0 that is beneath the division sign and multiply it times the number in front of the division sign. 0 * 0 = 0.

 

4. Take that 0 and write it directly under the first zero that you wrote and subtract the two. 0 - 0 = 0.

 

5. You can't go any further because there are no additional numbers under the division sign, and you have no remainder. 

 

Therefore, 220 divided by 11 is 20. 

 

 

Answer 3

Suppose you did the reciprocal.  Then you would dividing 220 by 11.

 

220 / 11 = 20

 

 

Therefore,

 

11 / 220 = 1 / 20

 

 

FYI, use the slash symbol to represent division.  You were using the radical sign, which indicates root numbers.
