<span>Joe got an hourly raise at work and his new rate will be $10.25 per hour. </span>If r represents the amount of the raise, then the following equation can be written: X=10.25-r where X is <span>Joe’s hourly rate was before his raise. Joe was paid (10.25-r) USD per hour before he got a raise.</span>
Their sum can be both equal, or greater. If you have 3/8 and 6/8, you would get 9/8 or 1 and 1/8. Which is greater than 1. Also if you add 2/6 and 4/6, you get 6/6 or 1. proving that both are possible.
