2/3 - 1/4 = 8/12 - 3/12 =5/12
To find the weight of the wood, subtract the weight of the empty trailer (1/4 ton) from the total weight of the trailer with the wood (2/3 ton), resulting in (5/12) ton. ;
The weight of the wood in the trailer is 12 5 ton, found by subtracting the weight of the empty trailer from the total weight. This subtraction involved converting the weights into fractions with a common denominator. Therefore, 3 2 − 4 1 = 12 5 .
