You do not need to estimate. 5 - 15 = -10 and any estimation would require at least as much effort.
5 - 15 = -10
100 50 mL bottles.
estimate of 24 mulitply by 15 = 300estimate of 24 = 2020 * 15 = 300
My estimate, based 15*17 is 25500.I can do 15*17 because it is 162-1.
I estimate 15 cm.
The best estimate is 15 centimeters which is about 6 inches
15% of 22 = 15% * 22 = 0.15 * 22 = 3.3

A more reasonable estimate would be 15.
