Answer:
5=NxC divided by 1/4 ( don't have division sign on computer)
Explanation:
First we now that it will start with 5=, because it says "5 is..." then we see that we have to multiply the number by c, sense it just says "...a number c" without an action so we assume its multiplication. Finally we divide NxC by 1/4 to fine one fourth of a number c, which equals five.
