A box of chocolate shortcake, the total weight of the box and sugar is 1.25 kg. After eating half the sugar, the total weight of the sugar and the box is 0.75 kg. How many kilograms of sugar and boxes are counted? Solution: Understand the meaning of the problem.

I ate half the sugar, and the sugar and the box weighed 0.75 Jin.

So half sugar weight 1.25-0.75 = 0.5kg.

So the sugar weight is 0.5*2= 1kg.

Container weight1.25-1= 0.25kg.

I hope I can help you! ! !
