a simple way to do away with denominators, is we can simply multiply both sides by the LCD, in this case the LCD is 3, so let's multiply both sides by 3.
First convert the numbers to get the same denominator 1/3=4/12 5/6=10/12 5/12 Then add them all together 4/12+10/12+5/12= 19/12 Then reduce 1 7/12 Your answer is 1 ton and 7/12 of a ton
