Let’s go step by step to round each decimal to the nearest hundredth.
Rounding to the nearest hundredth means we look at the
third digit after the decimal point (the thousandths place).
- If that digit is
5 or more, we round up the hundredths digit by 1.
- If it’s
less than 5, we leave the hundredths digit as it is.
Then we drop all digits after the hundredths place.
Let’s do each one:

Left Column:
1.
7.123 → Third digit is 3 (<5) → Keep 2 →
7.12
2.
18.901 → Third digit is 1 (<5) → Keep 0 →
18.90
3.
7.890 → Third digit is 0 (<5) → Keep 9 →
7.89
4.
12.346 → Third digit is 6 (≥5) → Round up 4 to 5 →
12.35
5.
1.569 → Third digit is 9 (≥5) → Round up 6 to 7 →
1.57
6.
18.620 → Third digit is 0 (<5) → Keep 2 →
18.62
7.
5.689 → Third digit is 9 (≥5) → Round up 8 to 9 →
5.69
8.
16.321 → Third digit is 1 (<5) → Keep 2 →
16.32
