First take the '5' in '65'. The number '81' times '5' gives you '405'. Then take the '6' in '65'. The number '81' times '6' gives you '486'.
Now add '405' and '486'. But you'll be shifting the '486' one place over to the left. So starting from the right on the upper adding line, the '5' from '405' has nothing to be added together with. So the result is '5'.
Go to the '0' in '405'. It needs to be added with the '6' of '486'. That gives you '6'.
Go to the '4' in '405'. It needs to be added with the '8' of '486'. That gives you '12'. Keep the '2' of '12', but carry the '1' over to the left.
There's nothing left from the adding line that has '405'. But you still have the '4' of '486' on the lower adding line. So you add the '1' of '12' to the '4' of '486'. That gives you '5'.
So your total is 5,265.
The average of the five numbers is 65 + 64 + 81 + 74 + 67 = 351/5 = 70.2.
1 goes into 81 81 times.

9 x 9 = 81 because if you count 9 times it would make up or be 81
If you mean: 9 times 9 = 81
81 x 65 = 5265
81: 1,3,9,27,8165: 1,5,13,65GCF: 1
How about: 9 times 9 = 81 or 81 times 1 = 81
5,265
81 times 7 or 7 times 81 equals 567
65/8 = 81/8
The average of the five numbers is 65 + 64 + 81 + 74 + 67 = 351/5 = 70.2.
1 - (2/3)4 = 1 - 16/81 = 65/81 ≈ 80.25%
It takes 81/65 = 1.2462 hours = approx 1 hour 15 minutes.
1 goes into 81 81 times.
81 times 8 = 648
