500(1.6) = 800 800(0.625) = 500

1) John's money x something = Robert's money We can find the something by dividing Robert's money by John's money. something = $\displaystyle \frac{800}{500} = 1 \frac{3}{5} = 1.6$ 2) This is the same question, except that this time we multiply Robert's money by something to get John's money (it's a different something) Robert's money x something = John's money however, the solution is calculated in a very similar way; we just divide John's money by Robert's money something = $\displaystyle \frac{500}{800} = \frac{5}{8} = 0.625$

1. Let Robert's money is $x$ times of John's money so, Robert's money = $x\times$ John's money $800=x\times 500$ $\dfrac{800}{500}=x=1.6$ 2. Let John's money is $y$ times of Robert's money so, John's money = $y\times$ Robert's money $500=y\times 800$ $\dfrac{500}{800}=y=0.625$
