First you have to make them both common denominators so you find a number that both work for 27 and 6. I decided to simplify them into improper fractions so I got 930/27 - 119/6 but since that didn't work I found that if I simplified 930/27 to 310/9 then I could use that to get a common denominator and I multiplied both numbers to change the denominator so that I have 1860/36 - 1071/36 = which equals 789/36 which I then simplified to 263/12 I am not sure if you can simplify it further but that is what I got :) hope it helps
S + g = 425 g = s + 25 ----------------- We will use the method of substitution: s + s + 25 = 425 2 s = 425 - 25 2 s = 400 s = 400 : 2 s = $425 g = 200 + 25 g = $225 Answer: Seiji earned $200 and Gavin earned $225.
