Question

The reciprocal of 2/3 is 3/2. If the reciprocal of 4x/5 is 1/20, what is x?

Answer 1

Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation
`(4x)/(5)=20` . From there we can solve for x.

Firstly, multiply both sides by 5:
`4x=100`

Next, divide both sides by 4 and your answer will be
`x=25`
