Ethan writes 1/6 of a page in 1/12 of a minute. How much time does it take him to write a full page?

1/2 minute

Step-by-step explanation:

1/6 page is multiplied by 6 to get 1 whole page, so you have to multiply the time 1/12 of a minute by 6 to get 1/2 minute.

1/2 min per page is his rate.

Step-by-step explanation:

We want to know how much time per 1 page,right? So just set up the ratio and solve.

mins    

page

are the units we want, so take our info and set up the ratio in that way:

1/12 min ÷ 1/6 page = ___ (Remember that to divide by a fraction is the same as to multiply by its inverse.) So we can flip the second fraction over and multiply:

1/12 * 6/1 = 6/12 = 1/2 min per page is his rate.

This answer makes sense because in the original units, the time number (1/12) is half of the pages number (1/6)
