Stanton Degregorio: You round to the first 2 significant figures. . .and substitute the rest of the values with insignificant value of 0. . .For examples. . .14 300 -> 14 0000.00624 -> 0.00620.6 -> 0.60 --- the extra "0" shows rounding to 2 s.f. . . .0.0465 -> 0.046 --- because 0.047 would be a biased rounding. . .And two from your homework. . .48120 -> 48 0000.042124 -> 0.042000Do you get it now. . .?...Show more
