The answer is 6/49 just multiply them. Negatives cancel each other.
Any multiple of 4 over the same multiple of 15.
Some possibilities are
.. 8/30
.. 12/45
.. 16/60

.. 24/90
.. 28/105
4 pencils . 4/9 of an hour = 4/9 of 60 minutes = 4/9 * 60 = 80/3 minutes
x pencils = ? . one hour = 60 minutes
14 * 60 = 80/3 * x /*3
14 * 60 * 3 = 80 * x
80 * x = 2520 /80
x = 2520 / 80
x = 31.5 pencils
The result would be 32 pencils in one hour.
