Explanation:
First, let's get the exact product:
5.9 * 8.28 = 48.852
Ten, let's get the estimated product:
5.9 will be rounded up giving us 6
8.28 will be rounded down giving us 8
Now the estimated product = 6 * 8 = 48
Based on the above calculations, we have:
estimate : 48
exact : 48.825
This corresponds to option B
Hope this helps :)
