hi guys im trying to work out 20/3x=4 ive tried 1.666 but that does not work, could you give me the method to work it out ,also can you give me the answer so that i can understand it.
Thanks
$\displaystyle \frac{20}{3x} = 4$
$\displaystyle 20 = 4 \times 3x$
$\displaystyle 20 = 12 x$
$\displaystyle \frac{20}{12} = x$
$\displaystyle x = 1,666....$
I guess you made a mistake when setting x = 1,666... into your equation.
Remember x is actually equal to 1,6666666666666666... into infinity
Rather try setting $\displaystyle \frac{5}{3}$ into it, which is equal to 1,666...
