Answer 2

Let's solve these expressions step by step using the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

1. $81÷9*27÷3$: First, perform the division: $81÷9 = 9$. Then, multiply: $9 * 27 = 243$. Finally, divide again: $243 ÷ 3 = 81$.

2. $72÷8*90÷9$: First, perform the division: $72÷8 = 9$. Then, multiply: $9 * 90 = 810$. Finally, divide again: $810 ÷ 9 = 90$.

3. $63÷9*64÷8$: First, perform the division: $63÷9 = 7$. Then, multiply: $7 * 64 = 448$. Finally, divide again: $448 ÷ 8 = 56$.

So, the results are:

1. $81÷9*27÷3 = 81$
2. $72÷8*90÷9 = 90$
3. $63÷9*64÷8 = 56$
