ted wrote a three-digit number. He divided it by 14, added 12, and multiplited by 20. His final anser was 600. what number did ted write?

Plese show me how t get the answer. thanks.

  • 5th grade math -

    just reverse the steps and do the inverse operation

    600 รท 20 = 30

    30-12 = 18

    18 * 14 = 252

    so Ted wrote 252

    check:
    252 divided by 14 is 18
    12 added to 18 is 30
    30 multiplied by 20 is 600
