To the nearest ten, 240
38 and 244
The front end estimate is 200. But estimating a single number, in isolation and without context, is a complete waste of time. It all comes down to the context of what needs to be done with the number.If I had to add 244 to 1 trillion, I would estimate it as 0.If I had to add 244 to 0.0000000001, I would use the number as given, or possibly 240. If I had to divide it by 4, I would estimate it as 240, because 240/4 = 60. If I had to divide it by 5, I would estimate it as 250, because 250/5 = 50.
Using the estimate of 244 for atomic mass, it is 283 moles.
15% off of 244 = 207.40 = 15% discount applied to 244 = 244 - (15% * 244) = 244 - (0.15 * 244) = 244 - 36.6 = 207.4 or 244 * 85% = 244 * 0.85 = 207.4
30% of 244 = 244*30/100 = 73.2
244
122x2=244 61x4=244
244 as a percentage of 97.6 is 250% But 97.6 as a percentage of 244 is 40%
737 + 244 = 981
15.620499351813308788259445471518 squared = 244
244 [lots] of 80 = 19520.
