Question 398127
Ok, starting with:
{{{x = 2/((1/40-1/45)*60)}}} Let's subtract the two fractions first:
{{{1/40-1/45}}} The LCD is 360, so...
{{{1(9)/40(9) - 1(8)/45(8) = 9/360-8/360}}}={{{1/360}}} Ok so far? So we have...
{{{x = 2/((1/360)*60)}}}
{{{x = 2/(1/6)}}}
{{{x = 2*6}}}
{{{x = 12}}}
Does this help?
