first round off the two numbers you are dividing to the nearest one. For example 9.5/1.5, round it off to 10/2 which will equal to 5.
Any number between 15,650,000 and 15,749,999 will round to 15,700,000 when rounded to the nearest hundred thousand.
5499. To round to the nearest thousand, the hundreds digit would be the decider: if 5 or more it would round up, 4 or less would round down. Need to round down, so the hundreds digit must be 4. The tens and units make no difference, so have them as large are possible, namely 9 each, to give: 5499 as the largest whole number that rounds to 5000 to the nearest 1000. A quick way is to observe 1000/2 = 500, so need to add 1 less than this (499) to the number and it will round down, that is 5000 + 1000/2 - 1 = 5000 + 500 - 1 = 5499.
the least number that round to 800000 is 750000 and the greatest number that round to 800000 is 849999.
