We can express that as a fraction, taking into account that dividing by 4 is equivalent as multipliying by 1/4 (because the 4 is in the lower part as denominator that is). So we have:
(7/6)/4 = (7/6)(1/4)
and now we only have to multiply numerators and denominators:
= 71/64
= 7/24
that is the result.
