Yes but, if you can, you should try to round one up and the other down. Unless that results in rounding well away from the number. For example, 48*62 Exact answer = 2976 If you round 48 up to 50, 62 down to 60 Estimate = 50*60 = 3000 (estimation error = +0.8%) But if you had 48*68 Exact answer = 3264 Round up and down: 50*60 = 3000 (estimation error = -8.1% ) Round down and up: 40*70 = 2800 (estimation error= -14.2%) Round up and up: 50*70 = 3500 (estimation error = +7.2%) The last still has a large error but it is the smallest of the these.
648 is rounded down to 600, which is the nearest hundred.This is because (6)48 is less than (6)50 so the number is rounded down to the previous hundred (600) and not the next (700).
