Step-by-step explanation:
To round a figure we must look specifically at what place value is the number immediately after the comma.
for example:
35,876 rounded round to the nearest thousand:
ANSWER:
As the figure that follows after the comma approaches 9, immediately add one unit to 5, transforming the number into an approximate value of 36,000
Now rounded to nearest 100:
35,900
to round to 100 we only look at the three-unit figures that correspond to the hundred, that is, the place value of the figure after the comma.
