Decimals like 1.4375 often appear in measurements, scaling calculations, engineering values, and technical specifications. While decimals are convenient for quick calculations, fractions are usually preferred when exact precision and clear representation matter.
So the key question is:
What is 1.4375 as a fraction?
In this guide, we’ll convert the decimal step by step, simplify it completely, verify the result, and explore practical situations where this conversion is useful.
Why Convert 1.4375 Into a Fraction?
Converting decimals into fractions is helpful when:
- Exact values are required without rounding
- Working with measurements and tolerances
- Solving algebraic or ratio-based problems
- Interpreting technical or engineering data
- Avoiding approximation errors
Fractions make values like 1.4375 easier to compare, scale, and communicate accurately.
Understanding the Decimal 1.4375
Before converting, let’s examine the number:
- 1.4375 is a terminating decimal
- It has four digits after the decimal point
- It can be converted exactly into a fraction
- It commonly appears in fraction-based measurement systems
Because the decimal terminates, the conversion will be precise.
Step 1: Write 1.4375 as a Fraction
Since there are four decimal places, place the number over 10,000:
1.4375 = 14375 / 10000
This fraction is correct but not yet in simplest form.
Step 2: Simplify the Fraction
To reduce the fraction, divide both numbers by their Greatest Common Divisor (GCD).
Both 14375 and 10000 are divisible by 625.
Divide both by 625:
- 14375 ÷ 625 = 23
- 10000 ÷ 625 = 16
✅ Final Simplified Fraction
1.4375 as a fraction (simplest form):
23 / 16
Optional: Convert to a Mixed Number
Since 23/16 is an improper fraction, it can also be written as a mixed number:
- 23 ÷ 16 = 1 remainder 7
- Mixed number = 1 7/16
So:
- Fraction form: 23/16
- Mixed number form: 1 7/16
Both represent the same value.
Step 3: Verify the Conversion
Decimal Check
23 ÷ 16 = 1.4375
✔ Exact match
Cross-Multiplication Check
- 14375 × 16 = 230000
- 23 × 10000 = 230000
✔ Both sides are equal, confirming correctness.
