I have three fraction questions that I need help with because I'm not good with fractions at all the question are,solve the equation for b, 11over12+b=5over6 and I don't know where to start.
\n" ); document.write( "------------
\n" ); document.write( "11/12 + b = 5/6
\n" ); document.write( "Multiply thru by 12 to get:
\n" ); document.write( "11 + 12b = 10
\n" ); document.write( "12b = -1
\n" ); document.write( "b = -1/12
\n" ); document.write( "=====================
\n" ); document.write( "The next one, solve the equation for f, f-(-7over10)=-4over5.
\n" ); document.write( "f-(-7/10) = (-4/5)
\n" ); document.write( "MUltiply thru by 10 to get:
\n" ); document.write( "10f - (-7) = -8
\n" ); document.write( "10f = -15
\n" ); document.write( "f = -3/2
\n" ); document.write( "===================\r
\n" ); document.write( "\n" ); document.write( "And the last one is, if c=5over6 and d=1 over 4,evaluate 8c over-d and that is the last question thank you for any help I can get.
\n" ); document.write( "c=5/6 and d=1/4,
\n" ); document.write( "Then (8c)/(-d)
\n" ); document.write( "=8(5/6)/(-1/4)
\n" ); document.write( "=(20/3)/(-1/4)
\n" ); document.write( "Invert the denominator and multiply to get:
\n" ); document.write( "= - 80/3
\n" ); document.write( "==============
\n" ); document.write( "Cheers,
