Understanding the Decimal
First, let’s take a closer look at the decimal itself. The number 0.5625 has four decimal places, which indicates how it can be converted to a fraction.
Step 1: Convert the Decimal to a Fraction
To convert 0.5625 to a fraction, we start by placing it over 1: [ \frac{0.5625}{1} ]
Next, to eliminate the decimal, we can multiply both the numerator and the denominator by 10, raised to the number of decimal places (which is 4 in this case): [ \frac{0.5625 \times 10000}{1 \times 10000} = \frac{5625}{10000} ]
Step 2: Simplify the Fraction
Now that we have a fraction, our next task is to simplify it. This can be done by finding the greatest common divisor (GCD) of the numerator (5625) and the denominator (10000).
Finding the GCD
We can find the GCD of 5625 and 10000 using the prime factorization method or the Euclidean algorithm.
- Prime Factorization:
- 5625 can be factored into ( 3^2 \times 5^4 ).
- 10000 can be factored into ( 10^4 = 2^4 \times 5^4 ).
Thus, the common factors are ( 5^4 ), which gives us a GCD of 625.
Dividing by the GCD
Now, divide both the numerator and the denominator by 625: [ \frac{5625 \div 625}{10000 \div 625} = \frac{9}{16} ]
Conclusion of the Conversion
Therefore, the decimal 0.5625 expressed in fraction form is: [ \frac{9}{16} ]
Key Points to Remember
- Always express the decimal as a fraction over 1 before eliminating the decimal.
- The GCD is essential for simplifying fractions.
- The process involves multiplying to eliminate decimals and then simplifying the resulting fraction.
