Having doubts that 100% is for sept or aug? So how do I tell my child to make the comparison and identify the actual 100%. (‘This was a 20% decrease from the number in August’ means there was a 20% decrease from the 100% in August. Ask your child in which month were there more visitors to ensure his/her understanding of the question/sentence.)
My understanding is 100% is aug while sept is 80% when making comparisons. Am I correct? (Yes, you are indeed correct.
100% – 20% = 80%——- 10000
100% ——- 12500
Ans : 12500 visitors.)
