Having trouble,Whats 1/3 (-2/4)

-1/6

Step-by-step explanation:

im assuming you meant multiply them? if so then

1         -2            -2           -1

---   *  ---    =       ---    =    ---

3         4              12          6

or

1/3=4/12 and -2/4=-6/12

4/12*-6/12=-24/144=-1/6

They will be able to have their break together in 60 minutes.

Step-by-step explanation:

You will have to find the least common multiple (LCM) between 20 and 30.

The prime factorization of 20 is: 2 x 2 x 5

The prime factorization of 30 is: 2 x 3 x 5

Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(20,20) = 60
