Question 1130342

Hi!I was wondering if you could please help me figure out this problem.My teacher assigned it to me but did very little explaining on how to do it.P.s-solving for c. 4/5 divided by c = 2/5.Thanks for the help
<pre>Just 1 CORRECT way to do this and that's using the SIMPLEST method. 
{{{matrix(1,19, (4/5)/c, "=", 2/5, "=====>", (4/5), "÷", c, "=", 2/5, "=====>", (4/5), "*", 1/c, "=", 2/5, "======>", 4/(5c), "=", 2/5)}}}
10c = 4(5) ------- Cross-multiplying
{{{highlight_green(matrix(1,5, c, "=", 4(5)/10, "=", 2))}}}
