one weighed = 879g 54 mg

second weighed = 98g 653mg

third weighed = 285g 6mg

total weight =

879.54g + 98.653g + 285.6g

= 1263.793g

Answer 2

Answer:

Explanation:

We know, 1 kg = 1000 grams

Now kg and g are converted into grams before doing subtraction and then we need to follow the simple subtraction process.

11 kg 460 g = (11 × 1000) g + 460 g = 11000 g + 460 g = 11460 grams

25 kg 765 g = (25 × 1000) g + 765 g = 25000 g + 765 g = 25765 grams

Now sum,

            25765 g

       -   11460 g

           14305 g

                    = 14 kg 305 g

Therefore, 25 kg 765 g - 11 kg 460 g = 11 kg 305 g
