Answer :
9 x 13 = 117
------------------
2.25 x 4 = 9
-------------------
Therefore:
2.25 x 4 x 13 =117
2.25 x 52 = 117
---------------------
Therefore:
117/(2.25) = 52
Therefore:
(2.25)/117 = 1/52
------------------
2.25 x 4 = 9
-------------------
Therefore:
2.25 x 4 x 13 =117
2.25 x 52 = 117
---------------------
Therefore:
117/(2.25) = 52
Therefore:
(2.25)/117 = 1/52
um...you could use long division. if u wanted the answer, then it is 52.
