Convert 7.3 into equivalent fractions and write it as a percentage value
1. Write the pure repeating (recurring) decimal number as a percentage.
Approximate to the desired number of decimal places (14).
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
7.33333333333333 =
7.33333333333333 × 100/100 =
(7.33333333333333 × 100)/100 =
733.333333333333/100 =
733.333333333333% ≈
733.33%
(rounded off to max. 2 decimal places)
- In other words:
- Approximate to the desired number of decimal places...
- Multiply the number by 100...
- ... And then add the percent sign, %
- 7.3 ≈ 733.33%
2. Write the pure repeating (recurring) decimal number as an improper fraction.
7.3 can be written as an improper fraction.
- The numerator is larger than or equal to the denominator.
Set up the first equation.
- Let y equal the decimal number:
y = 7.3
Set up the second equation.
- Number of decimal places repeating: 1
Multiply both sides of the first equation by 101 = 10
y = 7.3
10 × y = 10 × 7.3
10 × y = 73.3
Subtract the first equation from the second one.
- Having the same number of decimal places ...
- The repeating pattern drops off by subtracting the two equations.
10 × y - y = 73.3 - 7.3 ⇒
(10 - 1) × y = 73.3 - 7.3 ⇒
We now have a new equation:
9 × y = 66
Solve for y in the new equation.
9 × y = 66 ⇒
y = 66/9
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 7.3
According to our calculations:
y = 66/9
⇒ 7.3 = 66/9
3. Reduce (simplify) the fraction above:
66/9
to the lowest terms, to its simplest equivalent form, irreducible.
To reduce a fraction to the lowest terms divide the numerator and denominator by their greatest (highest) common factor (divisor), GCF.
Factor the numerator and denominator (prime factorization).
66 = 2 × 3 × 11
9 = 32
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (2 × 3 × 11; 32) = 3
Divide both the numerator and the denominator by their GCF.
66/9 =
(2 × 3 × 11)/32 =
((2 × 3 × 11) ÷ 3) / (32 ÷ 3) =
(2 × 11)/3 =
22/3
4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):
- A mixed number = an integer number and a proper fraction, of the same sign.
- Example 1: 2 1/5; Example 2: - 1 3/7.
- A proper fraction = the numerator is smaller than the denominator.
22 ÷ 3 = 7, remainder = 1 ⇒
22 = 7 × 3 + 1 ⇒
22/3 =
(7 × 3 + 1) / 3 =
(7 × 3) / 3 + 1/3 =
7 + 1/3 =
7 1/3
22/3 ~ Equivalent fractions.
- The above fraction cannot be reduced.
- That is, it has the smallest possible numerator and denominator.
By expanding it we can build up equivalent fractions.
Multiply the numerator & the denominator by the same number.
Example 1. By expanding the fraction by 5.
22/3 = (22 × 5)/(3 × 5) = 110/15
Example 2. By expanding the fraction by 6.
22/3 = (22 × 6)/(3 × 6) = 132/18
- Of course, the above fractions are reducing...
- ... to the initial fraction: 22/3
:: Final answer ::
Written in 4 different ways
As a reduced (simplified) positive improper fraction:
7.3 = 22/3
As a mixed number:
7.3 = 7 1/3
As a percentage:
7.3 ≈ 733.33%
As equivalent fractions:
7.3 = 22/3 = 110/15 = 132/18
