3/2 divided by 1/4 right?
It equals 3/8 if you simplify it to a decimal it's .375
Simplifying to a percent? Move decimal two places to the right. Between 7 and 5. 37.5%; You can round that if you like to the nearest percent, 38%
It's not what you asked for but that's just a little extra stuff. I hope that helps. :)
