hi can someone tell me how to put 18/48 in lowest terms and 16/40 in lowest terms

  • math -

    18/48

    Let's start by dividing the numerator and denominator by 2

    18/48 = 9/24

    That's still not the lowest terms. Now let's divide by 3.

    9/24 = 3/8

    I could have saved some time by dividing by 6 the first time.

    Now you can do the same with 16/40. What is the lowest terms for that fraction?

  • math -

    Keep dividing both the numerator and denominator by 2 or 3 or any other divisor they have in common until you can't divide evenly any more.

    18/48 = 9/24 = 3/8

    16/40 = ?

  • math -

    would it be 2/5

  • math -

    Right! 16/40 = 2/5

    THANK YOU

    You're welcome.
