Question 86529
Given:
.
{{{3/4}}} divided by {{{4/5}}}
.
To divide by a fraction you can invert that divisor and multiply it times the dividend.
Therefore, this division problem converts to the multiplication of the dividend {{{3/4}}} by
the inverted divisor which is now {{{5/4}}} ...
.
{{{(3/4) * (5/4)}}}
.
Just multiply the terms in the two numerators to get the resulting numerator, and also 
multiply the terms in the two denominators to get the resulting denominator. This makes
the problem become:
.
{{{(3*5)/(4*4) = 15/16}}}
.
So the correct answer is B ... {{{15/16}}}
.
