Remark
You have to read this carefully to know what way to write it.
One way you could write it would be
20 * x = 18 where x is the fraction. Now all you need do is divide.
Divide both sides by 20
20/20 * x = 18/20
But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.
18: 2 * 3 * 3
20: 2 * 2 *5
Cancel out the Highest common factor or 2.

Answer:
c = 37
Step-by-step explanation:
Pythagorean thm formula:
a² + b² = c²
Given:
a = 12
b = 35
Work:
a² + b² = c²
12² + 35² = c²
144 + 1225 = c²
c² = 1369
c = 37
