Find the product of .
Let the missing terms be denoted by .
When multiplying fractions, we can reduce the numerator of one of
the fractions with the denominator of another fraction.
In this example, we can reduce the denominator of each fraction
and the numerator of the fraction that follows.
All the numerators and denominators cancel each other out except
for the numerator of the first fraction (61) and the denominator
of the last fraction (92).
Hence, the product is .
