69 times 6 is 414.
1.5 times 69 is 103.5. This is one and a half times longer than a diameter of 69.
3 times 23 = 69
A reasonable estimate for 83*69 is 80*70 = 5600.The true figure, for comparison, is 5727.
It goes: 69/3 = 23 times
It is: 69 times 69 = 4761
The answer will depend on what you wish to do with the estimate. If, for example, you wished to divide by 101, I would suggest leave it as it is because 1313/101 = 13. On the other hand, if multiplying by 69, I suggest a good estimate is 1300. Then 1313*69 is approximated by 1300*70 = 91000.
