What is the sum of 2kg, 840kg,9kg ,460g and 920g

2 + 840 + 9 + 0.46 kg + 0.92 kg = 852.38 kilograms = 852,380 grams

To find the sum of these quantities, we need to convert the masses to the same unit.

First, let's convert 2kg, 840kg, and 9kg to grams:
2kg = 2000g
840kg = 840000g
9kg = 9000g

Now, let's convert 460 grams and 920 grams to kilograms:
460g = 0.46kg
920g = 0.92kg

Now we can add up all the converted values:

2000g + 840000g + 9000g + 460g + 920g = 852380g

To convert grams back to kilograms, we divide by 1000:

852380g รท 1000 = 852.38kg

Therefore, the sum of 2kg, 840kg, 9kg, 460g, and 920g is 852.38kg.

To find the sum of these values, you need to convert all the units to the same unit (grams in this case), and then add them together.

First, let's convert the kilograms to grams:
2kg = 2,000g
840kg = 840,000g
9kg = 9,000g

Next, let's convert the grams to grams (since they are already in grams):
460g = 460g
920g = 920g

Now, we can add the values together:
2,000g + 840,000g + 9,000g + 460g + 920g = 852,380g

Therefore, the sum of 2kg, 840kg, 9kg, 460g, and 920g is 852,380g.
