to multiple fractions we just keep them the same :
so we simplify do:
9/14 x 7/6 =
9x 7 = 63 ( numerator)
and 14x 6 = 84. (denominator)
giving us an answer of 63/84.
we then simplify 63/84 by dividing both numbers by 6.
giving us a total of :
9/14.
we can't simplify anymore so that's the final answer .
