Estimation is the key to PS success. Frequently, a question will test your ability not to compute, but rather to make reasonable approximations. For example, the fact that 11 goes into 76 a little more than 7 times means that 11/76 must be slightly less than 1/7.
The only problem here is that 11/76 is slightly GREATER than 1/7.
