720 6 digit numbers can be made with the number 888995.* * * * *No.720 numbers would have been the correct answer IF all 6 digits were different. But they are not. There is one triplet (so divided by 3! and one pair so divide by 2!The correct answer is therefore 6!/(3!*2!) = 720/(6*2) = 60
There are 6!/3! = 120 different 3-digit numbers that can be made from these 6 digits.
There are 6 because 6/3 = 2
1/2 ÷ 1/6 = 1/2 × 6/1 = (1×6)/(2×1) = 6/2 = 6 ÷ 2 = 3.
2 5/6 = 17/6 So there are 17 sixths in 2 5/6
