The decimal 0.75 appears frequently in everyday life — from prices and discounts to measurements, grades, and time tracking. You might see 0.75 hours, 0.75 liters, or 0.75 probability in different situations.
While decimals are convenient, fractions often make values easier to visualize, compare, and calculate, especially in math, cooking, construction, and scheduling.
So let’s answer the question clearly:
Why Convert 0.75 Into a Fraction?
Converting 0.75 into a fraction is helpful when:
- Solving math or exam problems
- Working with measurements or recipes
- Avoiding rounding errors
- Understanding proportions more clearly
- Using fractions instead of decimals in formulas
For example, 3/4 of an hour is often easier to understand than 0.75 hours.
Step 1: Write 0.75 as a Fraction
The decimal 0.75 has two digits after the decimal point, which means it represents hundredths.
So it can be written as:
0.75 = 75 / 100
This fraction correctly represents the decimal value, but it is not yet in simplest form.
Step 2: Simplify the Fraction
To simplify 75 / 100, we find the greatest common divisor (GCD) of the numerator and denominator.
Factors of 75:
1, 3, 5, 15, 25, 75
Factors of 100:
1, 2, 4, 5, 10, 20, 25, 50, 100
The greatest common divisor is 25.
Now divide both numbers by 25:
- 75 ÷ 25 = 3
- 100 ÷ 25 = 4
This gives the simplified fraction:
3 / 4
✅ Final Simplified Answer
0.75 as a fraction = 3 / 4
Step 3: Verify the Fraction
It’s always good practice to verify your result.
Decimal Check
Divide the numerator by the denominator:
3 ÷ 4 = 0.75
✔ This confirms the conversion is correct.
Cross-Multiplication Check
- 75 × 4 = 300
- 3 × 100 = 300
✔ Both sides match, confirming the fraction is accurate.
Is 3/4 the Simplest Form?
Yes.
The fraction 3 / 4 is already in its simplest form because 3 and 4 share no common factors other than 1.
