Not in this case.
Rounding the weights to 10 lb and 60 lb gives an estimated total weight of 70 lb. Using compatible numbers by rounding to 9 lb and 60 lb, the estimated total weight is 69 lb. The estimate using compatible numbers (69 lb) is closer to the actual total weight of 71.6 lb.
Estimate 43/81 by using compatible numbers
9 + 63 = 72 lbs.
Compatible numbers would be easier. Rounding gives you 14 x 47. Compatible numbers could be 13 x 50 which would be closer to the actual product.
To estimate quotients, round the dividend and the divisor to compatible numbers.
By rounding off.
we have to find compatible numbers
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.
by rounding off the numbers
By rounding each of the numbers involved.
