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?

Question

how do you find the answer to this math word problem?

Answer 1

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).

Answer 2

Let x = the # of minutes needed to complete one page

 

1/12 minutes       x minutes

---------------  = ---------------

1/6 page              1 page

 

Using cross multiplication

 

(1/12)(1)=(1/6)x

Multiply everything by 12

1=2x

 

x=1/2 minute
