You could use 250 and 750.
If you know the number is 7128 I do not understand why on earth anyone would want to estimate it!
250 and 750, which sum to 1000. The exact sum is 1001.

First of all, the two numbers are quite a long way from the ones whose quotient you are trying to estimate. Also, 8100 is smaller than 9269 so your estimate is going to be smaller than the actual value. And then 90 is bigger than 88 and is the denominator. This will make the estimate smaller still. Both the compatible numbers selected will reduce the stimate. They should be selected so that the effect of one acts in the opposite direction to that of the other. So, if you must use 8100, the select the second number which is smaller than 88. Or, if you must use 90, the other number should be greater than 9269.
The best estimate is, of course, the exact answer which is 19.075I would settle for 5*4 = 20.
The best way to estimate a quotient using compatible numbers is to first understand how compatible numbers work. They are numbers that are close in value to the actual numbers and are easily added, subtracted or divided.
i think it is 28x26

720/8 = 90

The best estimate for 540,123 would be 540,000. When estimating numbers, you typically round to the nearest place value you are interested in. In this case, rounding to the nearest thousand gives us 540,000 as the best estimate.
i think the answer is 600
The best estimate would, of course, be 249.
Yes, 50.4 can be estimated. In this case, you would round it to the nearest whole number, which would be 50. This is a common estimation technique when dealing with decimal numbers.
