Let's see. Estimating would start with rounding up 498. 498 will turn into 500. Next, we round 12. Twelve rounds to 10, so it ends up to become 500 divided by 10. 500 divided by 10 is 50. So, estimated, 498 divided by 12 would be somewhere near 50.
(by the way, 498 divided by 12 is actually, non-estimated, 41.5.)

5 over 12 (5/12) is the same as 5 divided by 12: 5 ÷ 12 = 0.4167
The product of 6 and 6 is 36 and the sum of 6 and 6 is 12 And so therefore: 36/12 = 3 which is the quotient

228 is a multiple of 12 so estimation is not necessary but if you must, then 240/12 = 20

35.7=36 11.4=12 36 divided by 12 = 3 The answer is 3.
5 over 12 (5/12) is the same as 5 divided by 12: 5 ÷ 12 = 0.4167

The answer is 3. 36 divided by 12 = 3
