Converting Ordinary Fractions to the Lowest Common Denominator

To convert ordinary fractions to the lowest common denominator, you need to find the least common multiple (LCM) of the denominators of the fractions. Once you have the LCM, you can use it as the common denominator for the fractions.

For the given example of ordinary fractions 9/40 and 7/50, the process involves finding the lowest common denominator.

Step 1: Find the Least Common Multiple (LCM) of the Denominators

The denominators are 40 and 50. To find the LCM, you can use various methods such as prime factorization, listing multiples, or using the method of division.

Step 2: Convert the Fractions to the Lowest Common Denominator

Once you have the LCM, you can convert the fractions to have the same denominator, which is the LCM.

Let's calculate the LCM of 40 and 50 to find the lowest common denominator for the fractions 9/40 and 7/50.

Calculating the Lowest Common Denominator

The LCM of 40 and 50 can be calculated using different methods. One common method is to use prime factorization.

The prime factorization of 40 is 2^3 * 5, and the prime factorization of 50 is 2 * 5^2.

The LCM is the product of the highest powers of all prime factors involved. Therefore, the LCM of 40 and 50 is 2^3 * 5^2 = 200.

Converting the Fractions to the Lowest Common Denominator

Now that we have the LCM, we can convert the fractions to have the same denominator, which is 200.

The fraction 9/40 can be converted to an equivalent fraction with a denominator of 200 by multiplying both the numerator and denominator by 5: (9 * 5) / (40 * 5) = 45/200.

Similarly, the fraction 7/50 can be converted to an equivalent fraction with a denominator of 200 by multiplying both the numerator and denominator by 4: (7 * 4) / (50 * 4) = 28/200.

Therefore, the ordinary fractions 9/40 and 7/50 can be converted to the lowest common denominator as 45/200 and 28/200, respectively.
