625 Solution as a Fraction
Rational numbers are numbers that can be expressed as a ratio of two integers. Fractions are a type of rational number where the numerator and denominator are both integers. In this article, we will discuss how to convert the decimal 625 into a fraction step by step.
Step 1: Understanding Decimal Place Value
Decimal place value is important to understand when converting decimals to fractions. The decimal point separates the whole number from the decimal portion. The digits to the right of the decimal point represent a fraction of a whole number. For example, in the number 625, the 5 is in the hundreds place, the 2 is in the tens place, and the 5 is in the ones place. The decimal point is after the ones place, indicating that the number is less than one.
Step 2: Converting the Decimal to a Fraction
To convert the decimal 625 to a fraction, we need to determine the place value of each digit. The decimal point is after the ones place, which means that 625 can be written as 625/1000. This is because the denominator of a fraction represents the total number of equal parts that make up a whole. In this case, the whole is 1, and there are 1000 equal parts.
Step 3: Simplifying the Fraction
The fraction 625/1000 can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 125. Dividing both sides of the fraction by 125 results in 5/8. This is the simplest form of the fraction, and it represents the same value as the decimal 625.
Step 4: Checking the Answer
To check that the fraction 5/8 is equivalent to the decimal 625, we can multiply 5/8 by 1000/1000. This results in (5 * 1000)/(8 * 1000) = 5000/8000. This fraction can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 1000. Dividing both sides of the fraction by 1000 results in 5/8, which is the same as the original fraction we found in step 3.
