What is 2 and 1/3 as a decimal and explain how you did what is 5/11 as a is 1/8 as a decimal. how do you know?

2 and 1/3 as a decimal is 2.33 recurring because the 2 can remain how it is and then you need to add on the 1/3; you can find out 1/3 by dividing 1 by 3 

5/11 as a decimal is 0.45 recurring because 5 divided by 11 is 0.45 recurring

1/8 as a decimal is 0.125 recurring because you can again, divide 1 by 8 to get 0.125 or if you know 1/4 is 0.25, you can halve that 

id say about 3-30 but that is just my opinon
