Math  missing fraction
posted by Renee .
Please advise how it is I go about finding the missing fraction. I get so confused. The problem is: N3/5=1/4
I know the LCD would be 20 but from there, I am lost. Thank you.

To get equivalent fractions, multiply the numerator and the denominator by the same number.
3/5
20/5 = 4
3 * 4 = 12
3/5 = 12/20
Do the same for 1/4
