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.
