55    64     73     now divide by 4 to find which has remainder of 1

73 y/o

Answer 2

Answer: 73

Step-by-step explanation:

I think she's 73? You have to take multiples of nine and see if they work! I did 72 since I knew that 72 goes into 9 equally and if she is 73 there would be a remainder of 1. After that, I stuck with 73 and since I knew that 18 times 4 is also 72, I knew that 73 divided by 4 would give me 18 with a remainder of 1.
