Answer:
3/7
Step-by-step explanation: You can reduce the given fraction by 2 but then you will have to keep reducing until you can no longer reduce.
Method 1: 18/2 = 9
9/3 = 3
42/2 = 21
21/3 = 7
Method 2: 18/6 = 3
42/6 = 7
Take a large number that both, the numerator and denominator are divisible by. Therefore, the answer in simplest form is 3/7.
Hope this explanation helps.
