What is 2/3 of 800 dollars
omeli [17]
2/3 of 800

The word 'of' generally means multiply, so then

(2/3) * 800

800 is like 800/1, the fraction, and when multiplying fractions we multiply the top of the first and the second together, and multiply the bottom of the first and second together (numerator, denominator).

\frac{2}{3} * \frac{800}{1}&#10;=\frac{1600}{3}&#10;=533.333333333333

You don't really need the 800/1, but that might make it more clear exactly what's happening.

Edit: So I'm not sure if it's just me or that LaTeX formatting actually doesn't render. If not,

(2\3)*(800/1) = 1600/3 = 533.333333
