You saw on the previous page that 2/11=0.18. Show how you can use what you know about the decimal for 2/11 to find the decimal for 1/11

1/11 is half of 2/11. (1/11 + 1/11 = 2/11)

As 2/11 = 0.18, 1/11 must equal half of 0.18.

Half of 0.18 is 0.09. Thus the decimal for 1/11 is 0.09.

The decimal for 1/11 is 0.09

Step-by-step explanation:

We have two options to get the answer, the first one is when we know that 1/11 is half of 2/11, so 1/11 will be half of 0.18. We have to divide 0.18 by 2:

0.18:2 = 0.09

The other way to do it is to divide 1:11 = 1/11

The answer is 0.09
