Given 5/3, we want to know which of 20/12,15/9, or 10/6 are equivalent fractions:

**Each of these is equivalent to 5/3.**

Fractions are equivalent if they have the same decimal expansion. In each case the decimal for the fraction is `1.bar(6) `

Also note that in each case we can multiply 5/3 by some form of 1 to get the other fraction:

`5/3 * 4/4=20/12 `

`5/3*3/3=15/9 `

`5/3*2/2=10/6 `

Since 1 is the multiplicative identity (multiplying by 1 does not change the value) each of these represent the same real number.
