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.
just reverse the steps and do the inverse operation
600 ÷ 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
