Answer 1

3/30=1/10

The value of a dime is 1/10 the value of a dollar.

Answer 2

Relationship between the value of a dollar and the value of a dime is:

1 dollar= 10 dimes

or 1 dime= 0.1 dollars

Explanation:

We are given that:

Lisa exchanged 3 dollars for 30 dimes

3 dollars= 30 dimes

Dividing both sides by 3, we get

`(3)/(3)\ dollars=(30)/(3)\ dimes`

i.e. 1 dollar= 10 dimes

or 1 dime= 0.1 dollars

Hence, relationship between the value of a dollar and the value of a dime is:

1 dollar= 10 dimes

or 1 dime= 0.1 dollars
