Rounding a number to the nearest significant figure means rounding it to the nearest digit that indicates the precision of the measurement. This typically involves looking at the significant figures in the number and rounding to the appropriate level of precision. For example, 345.678 rounded to the nearest significant figure would be 300.
when rounding you want to choose an answer with the lowest significant figures to have a better answer choice
8 By definition, all the figures are significant (no rounding off appears to have taken place). There are eight significant figures.
That depends how many significant figures you are rounding to.
Keep the first three digits, replace the remaining digits with zero - rounding up or down as appropriate.
273.821 contains 6 significant figures. Rounding that to Hundredths (5 sig. figures) it becomes 273.82 Rounding it to Tenths (4 sig. figures) it becomes 273.8 And Rounding it to the nearest whole number (3 sig. figures) it becomes 274 etc., etc.
