Answer 2

For this case we must indicate which equations can be used to change the fraction
`\frac {3} {4}` to percentage.

For this, we make a rule of three:

1 ----------------------> 100%

\ frac {3} {4} -------> x

`x = \frac {\frac {3} {4} * 100} {1}`

This is equivalent to:

`x = \frac {3} {4} * 100`

If we divide between 100 on both sides of the equation, we have:

`\frac {x} {100} = \frac {3} {4}`

Option B

Answer:

`\frac {x} {100} = \frac {3} {4}`

Option B
