Convert 1.119 into equivalent fractions and write it as a percentage value
1. Write the mixed repeating (recurring) decimal number as a percentage.
Approximate to the desired number of decimal places.
Multiply the number by 100/100.
- The value of the number does not change when multiplying by 100/100.
- Note: 100/100 = 1
1.12 =
1.12 × 100/100 =
(1.12 × 100)/100 =
112/100 =
112%
- In other words:
- Approximate to the desired number of decimal places...
- Multiply the number by 100...
- ... And then add the percent sign, %
- 1.119 ≈ 112%
2. Write the mixed repeating (recurring) decimal number as an improper fraction.
1.119 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 = 1.119
Set up the second equation.
- Number of decimal places repeating: 1
Multiply both sides of the first equation by 101 = 10
y = 1.119
10 × y = 10 × 1.119
10 × y = 11.19
Get the same number of decimal places as for y:
10 × y = 11.199
Note: 11.199 = 11.19
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 = 11.199 - 1.119 ⇒
(10 - 1) × y = 11.199 - 1.119 ⇒
We now have a new equation:
9 × y = 10.08
Solve for y in the new equation.
9 × y = 10.08 ⇒
y = 10.08/9
Let the result written as a fraction.
Now we can write the number as a fraction.
According to our first equation:
y = 1.119
According to our calculations:
y = 10.08/9
⇒ 1.119 = 10.08/9
Get rid of the decimal places in the fraction above.
- Multiply the top and the bottom number by 100.
- 1 followed by as many 0-s as the number of digits after the decimal point.
1.119 = (10.08 × 100)/(9 × 100)
1.119 = 1,008/900
3. Reduce (simplify) the fraction above:
1,008/900
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).
1,008 = 24 × 32 × 7
900 = 22 × 32 × 52
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (24 × 32 × 7; 22 × 32 × 52) = 22 × 32
Divide both the numerator and the denominator by their GCF.
1,008/900 =
(24 × 32 × 7)/(22 × 32 × 52) =
((24 × 32 × 7) ÷ (22 × 32)) / ((22 × 32 × 52) ÷ (22 × 32)) =
(22 × 7)/52 =
28/25
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.
28 ÷ 25 = 1, remainder = 3 ⇒
28 = 1 × 25 + 3 ⇒
28/25 =
(1 × 25 + 3) / 25 =
(1 × 25) / 25 + 3/25 =
1 + 3/25 =
1 3/25
28/25 ~ 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 2.
28/25 = (28 × 2)/(25 × 2) = 56/50
Example 2. By expanding the fraction by 4.
28/25 = (28 × 4)/(25 × 4) = 112/100
- Of course, the above fractions are reducing...
- ... to the initial fraction: 28/25
:: Final answer ::
