Advice

When we are rounding we look at the first digit that we might discard. If it is $5$ or greater we round up. If it is less than $5$ we round down.

a) To round to the nearest whole number, we look at the first decimal place to decide whether to round up or down.

b) To round to one decimal place, we look at the second decimal place to decide whether to round up or down.

c) To round to two decimal places, we look at the third decimal place to decide whether to round up or down.

d) To round to three decimal places, we look at the fourth decimal place to decide whether to round up or down.
