    Certainly, let’s find a common denominator for the fractions 2/5 and 3/7.

    To find a common denominator, we need to find the least common multiple (LCM) of the denominators 5 and 7.

    The steps are as follows:

    1. List the prime factors of the denominators:

      • 5 = 5
      • 7 = 7
    2. Find the LCM by taking the highest power of each prime factor:

      • LCM = 5 × 7 = 35
    3. The common denominator is 35.

    Now, we can convert the fractions to have the common denominator of 35:

    2/5 = 14/35
    3/7 = 15/35

    So, the common denominator for the fractions 2/5 and 3/7 is 35.
