    Study Notes

    Adding Fractions

    • To add fractions, find a common denominator to combine them effectively.

    Sum of Fractions

    • The sum of the fractions (\frac{3}{5}) and (\frac{2}{7}) can be computed by finding a common denominator and adjusting the numerators accordingly.

    Least Common Denominator (LCD)

    • The least common denominator of (\frac{3}{5}) and (\frac{2}{7}) is 35. This is the smallest multiple that both denominators (5 and 7) share.

    Conversion to Equivalent Fraction

    • Converting (\frac{3}{5}) to a denominator of 35 involves multiplying both the numerator and denominator by 7, resulting in the equivalent fraction (\frac{21}{35}).

    First Step in Adding Fractions

    • The initial step in adding (\frac{3}{5}) and (\frac{2}{7}) includes finding the least common denominator (LCD) to create fractions with a shared base.

    New Numerators After Finding Common Denominator

    • When adding the fractions with a common denominator of 35, the new numerator for (\frac{3}{5}) is 21; for (\frac{2}{7}), it is 10, resulting in the adjusted fractions (\frac{21}{35}) and (\frac{10}{35}) respectively.
