Subtract and Simplify
2/3 - 1/5 = 1/2

  • Math (Check -

    Not quite.

    The common denominator 15 (the smallest number divisible by both 3 and 5).

    Since 15 divided by 3 is 5, then you multiply the numerator by 5.

    Since 15 divided by 5 is 3, then you multiply the numerator by 3.

    2/3 - 1/5 = 10/15 - 3/15 = 7/15
