How do you know that 8100 and 90 are not the best compatible numb...
First of all, the two numbers are quite a long way from the ones whose quotient you are trying to estimate. Also, 8100 is smaller than 9269 so your estimate is going to be smaller than the actual value. And then 90 is bigger than 88 and is ... Read More »

Let's pick a compatible number close to 7. I'll choose 6. 144 / 6 = 24 Now let's pick another one on the other side of 7. How about 8? 144 / 8 = 18 So, 144 / 7 will be somewhere between 18 and 24. Take a stab at it. Eryk
