Let's solve the problem step by step.
We are asked to
round each decimal number to the nearest whole number.
🔁 Rounding Rule:
To round a decimal to the nearest whole number:
- Look at the
tenths place (the first digit after the decimal point).
- If it is
5 or greater, round
up.
- If it is
less than 5, round
down.

Now, let’s go through each number:
1.
2.94
→ Tenths digit = 9 → ≥ 5 → Round up
→ 2 + 1 =
3
2.
34.33
→ Tenths digit = 3 → < 5 → Round down
→
34
3.
44.9
→ Tenths digit = 9 → ≥ 5 → Round up
→ 44 + 1 =
45
4.
17.723
→ Tenths digit = 7 → ≥ 5 → Round up
→ 17 + 1 =
18
5.
59.04
→ Tenths digit = 0 → < 5 → Round down
→
59
6.
119.6
→ Tenths digit = 6 → ≥ 5 → Round up
→ 119 + 1 =
120
7.
39.672
→ Tenths digit = 6 → ≥ 5 → Round up
→ 39 + 1 =
40
8.
88.667
→ Tenths digit = 6 → ≥ 5 → Round up
→ 88 + 1 =
89
9.
68.841
→ Tenths digit = 8 → ≥ 5 → Round up
→ 68 + 1 =
69
10.
0.993
→ Tenths digit = 9 → ≥ 5 → Round up
→ 0 + 1 =
1
11.
1.137
→ Tenths digit = 1 → < 5 → Round down
→
1
12.
80.82
→ Tenths digit = 8 → ≥ 5 → Round up
→ 80 + 1 =
81
13.
39.762
→ Tenths digit = 7 → ≥ 5 → Round up
→ 39 + 1 =
40
14.
72.93
→ Tenths digit = 9 → ≥ 5 → Round up
→ 72 + 1 =
73
15.
8.72
→ Tenths digit = 7 → ≥ 5 → Round up
→ 8 + 1 =
9
16.
6.6794
→ Tenths digit = 6 → ≥ 5 → Round up
→ 6 + 1 =
7
17.
3.898
→ Tenths digit = 8 → ≥ 5 → Round up
→ 3 + 1 =
4
18.
2.93
→ Tenths digit = 9 → ≥ 5 → Round up
→ 2 + 1 =
3
