Question

Lynn can type 60 words per minute. If she types for 30 minutes, how many words does she type in all?

Answer 1

Answer:1800 words

Step-by-step explanation:

Multiply how many words per minute she types by how many minutes she types. In this case 60x30=?. The easy way to do this is drop the 2 zeros and do  6x3=18. In the original equation we dropped the 2 zeros. Now we add them back on the back of the 18 and get 1800.
