When rounding to a given number of decimal places
\nWhen rounding to a given number of decimal places, do the following
\nLook at the next number after the last number of the decimal places you need to round to
\nIf the number is 5 or greater, round up, if it is than 5, leave as is; i.e.
\nround to 3 decimal places the following
\n$0.0055 = 0.006$
\n$0.0071 = 0.007$
\n\nWhen rounding to a given number of significant figures
\nWhen rounding to a given number of significant figures, do the following
\nLook at the next number after the last number of the significant figuresyou need to round to
\nIf the number is 5 or greater, round up, if it is than 5, leave as is; i.e.
\nN.B. Remember to keep the number you rounded to the significant number of places in the same unit e.g. 10's, 100's etc
\nround to 3 significant figures the following
\n$2573 = 2570$
\n$7828 = 7830$
\nround to 1 significant figures the following
\n$15 = 20$
\n$38851 = 40000$
