Final answer:
18% of 30 is equal to 30% of 18.
Step-by-step explanation:
In order to justify whether 18% of 30 is the same as 30% of 18, we need to calculate both values.
18% of 30 is found by multiplying 18% (or 0.18) by 30: 0.18 x 30 = 5.4.
30% of 18 is found by multiplying 30% (or 0.3) by 18: 0.3 x 18 = 5.4.
Both calculations result in the same value, 5.4, so 18% of 30 is equal to 30% of 18. Therefore, the conclusions are justified.
