To find:

the expanded form of the length of the chalk at the beginning of the lesson and at the end of the lesson,

Solution:

(a)

Given that the length of the chalk is 4.875 inches at the beginning of the lesson.

So, the expanded form of 4.875 is:

`4+(8)/(10)+(7)/(100)+(5)/(1000)`

(b)

Given that the length of the chalk is 3.125 inches at the end of the lesson

So, the expanded form of 3.125 is:

`3+(1)/(10)+(2)/(100)+(5)/(1000)`
