Question 1067904
.
A road is to be constructed with 15 1/2
m3 of crushed rock. If a small truck can carry 2 1/3
m3 of crushed rock, how many truckloads will be
needed?
~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{15}}} {{{1/2}}} = {{{31/2}}}.


{{{2}}} {{{1/3}}} = {{{7/3}}}.


Therefore,  {{{15}}} {{{1/2}}} : {{{2}}} {{{1/3}}} = {{{((31/2))/((7/3))}}} = {{{(31*3)/(2*7)}}} = {{{93/14}}} = 6.64 . . . 


7 truckloads is enough.
