It’s just a couple of multiplications. 16*67 is the same as 16*64 + 16*3, or 1024 + 48, or 1072. 29*37 is a little trickier, but it’s the same as 33^2 - 4^2. 33 is almost 1/3 of 100, so 33 squared is almost 1/9 of 10,000, which would be 1111… but it has to end in a 9, and be a multiple of 9, so it’s clearly 1089. 1089 - 16 is 1073. Since 37 * 29 > 16*67, it follows that 29/67 > 16/37.
Although, those numbers are so close that I don’t think that’s coincidence, so that probably was the way that @Timz set up the problem.
