What are the equivalent fractions for 1/2 and 1/5 using the least common denominators?

5/10 and 2/10

Step-by-step explanation:

To find equivalent fractions you need to first find the least common denominator. The LCD is always the least common multiple. In this case,  the LCM is 10. Also, it is important to remember that if you multiply one part of a fraction, like a denominator, by a number, you must also multiply the other part.

To get a fraction equal to 1/2 with a denominator of 10, you must multiply the numerator and denominator by 5. This creates the new fraction, 5/10. Then, do this same process with 1/5. To get the denominator of 10 you must multiply the fraction by 2. Thus, 2/10 is the new fraction.
