The decimal 1.6 appears often in everyday life — 1.6 kilometers, 1.6 hours, 1.6 liters, or ratings and scores. While decimals are convenient, many math problems, measurements, and instructions prefer fractions because they are exact and easier to visualize.
So the key question is:
What is 1.6 as a fraction?
Let’s convert it step by step, simplify it correctly, verify the result, and explore where this conversion is commonly used.
Why Convert 1.6 Into a Fraction?
Converting decimals to fractions is helpful when:
- Working with exact values (no rounding)
- Solving math equations and ratios
- Measuring time, distance, or ingredients
- Preparing for exams or homework
For example, 1⅗ hours is often easier to understand than 1.6 hours when planning schedules.
Step 1: Write 1.6 as a Fraction
The decimal 1.6 has one digit after the decimal point, which means it represents tenths.
So we write:
1.6 = 16 / 10
This fraction correctly represents the decimal value, but it is not yet simplified.
Step 2: Simplify the Fraction
To simplify 16 / 10, find the greatest common divisor (GCD).
Factors of 16:
1, 2, 4, 8, 16
Factors of 10:
1, 2, 5, 10
The greatest common factor is 2.
Now divide both numbers by 2:
- 16 ÷ 2 = 8
- 10 ÷ 2 = 5
This gives:
8 / 5
✅ Final Simplified Fraction
1.6 as a fraction = 8 / 5
Optional: Convert to a Mixed Number
Since 8 / 5 is an improper fraction, it can also be written as a mixed number.
Divide 8 by 5:
- 5 goes into 8 once, with 3 left over
So:
8 / 5 = 1 3 / 5
Both forms represent the same value:
- 1.6
- 8 / 5
- 1 3 / 5
Step 3: Verify the Answer
Verification ensures the conversion is correct.
Decimal Check
Divide the numerator by the denominator:
8 ÷ 5 = 1.6
✔ Correct
Cross-Multiplication Check
- 16 × 5 = 80
- 10 × 8 = 80
✔ Both sides match, confirming accuracy.
