You can use this formula :

$5^n$

Now we can apply the formula

${ 5 }^{ -1 }\qquad { 5 }^{ 0 }\qquad { 5 }^{ 1 }\qquad { 5 }^{ 2 }\qquad { 5 }^{ 3 }\\ \downarrow \qquad \quad \downarrow \qquad \downarrow \qquad \quad \downarrow \qquad \downarrow \\ 0.2\qquad 1\qquad 5\qquad \quad 25\qquad 125$

The rule is (from left to right) multiply th number by 5 to get the next number

So from right to left it will be divide by 5

1÷5=0.2
