Answer:
8/9
Step-by-step explanation:
find the highest common factor of the numerator and denominator and then divide both by that factor
Listing factors of numerator and denominator
16: 1,2,4,8,16
18: 1,2,6,9,18
from the above we can see that the HCF is 2, so divide numerator and denominator by 2
16/18 (divide numerator and denominator by 2)
= 8/9 (simplified)
