18/(6/13) = 18*13/6 = (18/6)*13
-64*5/4 = (-64/4)*5

18/1 divided by 6/13=
18/1 x 13/6 = 234/6
234 divided by 6= 39
39 is your answer.
You got the right answer.
And the second problem:
-64/1 times 5/4
Multiply across.
-64 times 5 equals -260
1 times 4 equals 4
You now have -260/4
Divide -260 by 4.
65 is your answer.

18/(6/13) = (18/1)/(6/13) = (18/1)*(13/6) = (234/6) = 39
-64 * (5/4) = (-320/4) = -80
