Enter values below:
You multiplied 28 x 3.50 and got 98.
Is this reasonable?
Round 28 down:
20
Round 3.50 down:
3.00
Multiplying our estimates, we have:
20 x 3.00 = 60
Calculate the residual of 28
28 - 20 = 8
Multiply this by 3.00
8 * 3.00 = 24
Calculate the residual of 3.50
3.50 - 3.00 = 0.5
Multiply this by 20
0.5 * 20 = 10
Add our 2 residual products:
24 + 10 = 34
Add residual product to estimate:
60 + 34 = 94
Evaluate our estimate of 98.
94 ≤ 98.
this seems reasonable
What is the Answer?
94 ≤ 98.
this seems reasonable
