Convert 74.29 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.

74.29 ≈ 74.3


Multiply the number by 100/100.

  • The value of the number does not change when multiplying by 100/100.
  • Note: 100/100 = 1

74.3 =

74.3 × 100/100 =

(74.3 × 100)/100 =

7,430/100 =

7,430%


  • In other words:
  • Approximate to the desired number of decimal places...
  • Multiply the number by 100...
  • ... And then add the percent sign, %
  • 74.29 ≈ 7,430%

2. Write the mixed repeating (recurring) decimal number as an improper fraction.

  • 74.29 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 = 74.29


Set up the second equation.

  • Number of decimal places repeating: 1

  • Multiply both sides of the first equation by 101 = 10


y = 74.29

10 × y = 10 × 74.29

10 × y = 742.9

Get the same number of decimal places as for y:

10 × y = 742.99

Note: 742.99 = 742.9


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 = 742.99 - 74.29 ⇒

(10 - 1) × y = 742.99 - 74.29 ⇒

We now have a new equation:

9 × y = 668.7


Solve for y in the new equation.

9 × y = 668.7 ⇒

y = 668.7/9

Let the result written as a fraction.



Now we can write the number as a fraction.

According to our first equation:

y = 74.29

According to our calculations:

y = 668.7/9

⇒ 74.29 = 668.7/9


Get rid of the decimal places in the fraction above.

  • Multiply the top and the bottom number by 10.
  • 1 followed by as many 0-s as the number of digits after the decimal point.

74.29 = (668.7 × 10)/(9 × 10)

74.29 = 6,687/90


3. Reduce (simplify) the fraction above:
6,687/90
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).

6,687 = 32 × 743

90 = 2 × 32 × 5

Calculate the greatest (highest) common factor (divisor), GCF.

Multiply all the common prime factors by the lowest exponents.

GCF (32 × 743; 2 × 32 × 5) = 32


» Calculate the greatest (highest) common factor (divisor), GCF, online calculator


Divide both the numerator and the denominator by their GCF.

6,687/90 =

(32 × 743)/(2 × 32 × 5) =

((32 × 743) ÷ 32) / ((2 × 32 × 5) ÷ 32) =

743/(2 × 5) =

743/10


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.

743 ÷ 10 = 74, remainder = 3 ⇒

743 = 74 × 10 + 3 ⇒

743/10 =

(74 × 10 + 3) / 10 =

(74 × 10) / 10 + 3/10 =

74 + 3/10 =

74 3/10


743/10 ~ 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 4.

743/10 = (743 × 4)/(10 × 4) = 2,972/40

Example 2. By expanding the fraction by 6.

743/10 = (743 × 6)/(10 × 6) = 4,458/60

  • Of course, the above fractions are reducing...
  • ... to the initial fraction: 743/10
