Answer:
40615
Step-by-step explanation:
Note, rounding off decimals involves observing if the said decimal is up to the value of 5. If it is, then it can be rounded up, if not, its rounded off.
Since we need to round the numbers to the second decimal before performing the operation, we will have, 8123÷0.2
Note, 8123 has no decimal so we ignore
But 0.211 has a second decimal which is the first 1 so because it's not up to 5, we round it off to 0.
Hence we have 8123 ÷ 0.2= 40615.0
Since our answer has no decimal, we leave it like that.
