how do I explain how to solve the following problem

Math 
Avery,
how to write 0.09 3/40.5 1/3 2/5

For Avery  Math 
Reiny,
Please do not append a new question to end of somebody else's post

For Mattie  Math 
Reiny,
2 X 10 square + 3 X 10 to the first + 5 X 10 to the zero +7 X 10 to the negative one
in "math"
= 2(10^2) + 3(10) + 5(10^0) + 7(10^1)
= 200 + 30 + 5 + 7/10
=235.7
looks like we have the number 235.7
decomposed into its different position values.
