65 - 9 = 56
It is 5 + 4 = 9.
Their average is 22 and their difference is 9 so use 22 and 9 13*31 = 222 - 92 = 484 - 81 = 403
9 + 63 = 72 lbs.
The front end estimate is 100. But estimating a single number, in isolation and without context, is a complete waste of time. If I had to add 117 to 1 trillion, I would estimate it as 0. If I had to add 117 to 0.0000000001, I would use the number as given - not use an estimate.Also, if I had to divided the number by 13 I would use 117 since 117/13 = 9 but if I had to divided it by 24 I might estimate it as 120 because 120/24 = 5.
65 - 9 = 56
9X60
It is 5 + 4 = 9.
8/11 + 3/9 8/11 + 3/9
9+63+863+9
An estimate of 8.99 would be 9, as it is the closest whole number to 8.99. When estimating numbers, it is common practice to round to the nearest whole number for simplicity. In this case, rounding 8.99 to the nearest whole number results in 9.
The estimated answer is 20.
Their average is 22 and their difference is 9 so use 22 and 9 13*31 = 222 - 92 = 484 - 81 = 403
9 + 63 = 72 lbs.
