Can someone help me find the technique or techniques used in this problem? 146 divided by 68. I thought that 14 and 7 are easy to divide, so I used 140 divided by 70, which is 2. The quotient is about 2.

were do you get 14 and 7 from 146 and 68?

you are using the technique of "approximation"
I usually glance at the numbers, in this case 140 is close to 146 and 70 is close to 68
and 140/70 = 14/7 = 2
(actual answer: 2.147)
