all will be rounded upward. I can check your work.
Now on the first, the common rule is if the estimated digit is 5, round up, and in the first one 3.7
However, this forces you to round up 5/9 of the time, and forces a bias upward. So some thinking texts change that rounding rule whken it is a 5, to round to the nearest even number.
examples 92.45 rounds to 92.4
90.5 rounds to 90
91.5 round to 92 and so on. If you are handling data, frankly this rule makes more sense. However, on student grades half the class doesn't like it, because their grades are rounded DOWN.
round of the following digits-
3.65*105(upto are place of decimal)
0.882026(upto three significant figures)
311.299(upto four significant figures)
4.783(upto two significant figures)
