Let’s solve each problem step by step. We’re converting mixed numbers (like 58 5/10) into decimals.
Remember:
A mixed number has a whole number and a fraction.
To convert to decimal, keep the whole number as is, then turn the fraction into a decimal by dividing the top by the bottom — or just move the decimal point if the denominator is 10 or 100.

Rule for denominators:
- If denominator is
10, put the numerator in the tenths place → e.g., 5/10 = 0.5
- If denominator is
100, put the numerator in the hundredths place → e.g., 87/100 = 0.87
Now let’s go one by one:
---
1.
58 5/10
Whole number: 58
Fraction: 5/10 = 0.5
→ 58 + 0.5 =
58.5
2.
26 87/100
Whole number: 26
Fraction: 87/100 = 0.87
→ 26 + 0.87 =
26.87
3.
38 7/10
Whole number: 38
Fraction: 7/10 = 0.7
→ 38 + 0.7 =
38.7
4.
85 5/100
Whole number: 85
Fraction: 5/100 = 0.05
→ 85 + 0.05 =
85.05
5.
22 1/10
Whole number: 22
Fraction: 1/10 = 0.1
→ 22 + 0.1 =
22.1
6.
25 47/100
Whole number: 25
Fraction: 47/100 = 0.47
→ 25 + 0.47 =
25.47
7.
92 2/10
Whole number: 92
Fraction: 2/10 = 0.2
→ 92 + 0.2 =
92.2
8.
24 5/10
Whole number: 24
Fraction: 5/10 = 0.5
→ 24 + 0.5 =
24.5
9.
25 46/100
Whole number: 25
Fraction: 46/100 = 0.46
→ 25 + 0.46 =
25.46
10.
81 5/10
Whole number: 81
Fraction: 5/10 = 0.5
→ 81 + 0.5 =
81.5
11.
17 12/100
Whole number: 17
Fraction: 12/100 = 0.12
→ 17 + 0.12 =
17.12
12.
98 5/10
Whole number: 98
Fraction: 5/10 = 0.5
→ 98 + 0.5 =
98.5
13.
56 24/100
Whole number: 56
Fraction: 24/100 = 0.24
→ 56 + 0.24 =
56.24
14.
50 38/100
Whole number: 50
Fraction: 38/100 = 0.38
→ 50 + 0.38 =
50.38
15.
78 8/10
Whole number: 78
Fraction: 8/10 = 0.8
→ 78 + 0.8 =
78.8
16.
47 2/10
Whole number: 47
Fraction: 2/10 = 0.2
→ 47 + 0.2 =
47.2
17.
30 36/100
Whole number: 30
Fraction: 36/100 = 0.36
→ 30 + 0.36 =
30.36
18.
63 70/100
Whole number: 63
Fraction: 70/100 = 0.70 → which is same as 0.7
→ 63 + 0.7 =
63.7
