Question 882660
{{{(23/100)8040+(42/100)545=(X/100)(3000)}}}
{{{1849.2+228.9=30X}}}
{{{30X=2078.1}}}
{{{x=69.27}}}

The hour hand makes one rotation every 12 hours.
{{{72=12*N}}}
{{{N=6}}} rotations.

I think you mean {{{3/4}}} and {{{2/5}}} of the same number.
{{{(3/4)X-(2/5)X=9}}}
Multiply both sides by {{{4*5}}}
{{{15X-8X=180}}}
{{{7X=180}}}
{{{X=180/7}}
.
.
.

{{{A=5x}}}
{{{B=12x}}}
{{{C=3(5.5x)=16.5x}}}
.
.
.

{{{A+B+C=2010}}}
{{{5x+12x+16.5x=2010}}}
{{{33.5x=2010}}}
{{{x=60}}}
So then,
{{{C-B=16.5x-12x=3.5x}}}
{{{C-B=3.5(60)}}}
{{{C-B=210}}}
