4 kg - 400 g = 2400 g 2600 g 3600 g 3400 g Both the qu

SOLUTION

Both the quantities have different units 4 kg and 400 g.

So, convert 4 kg to grams.

We know that, 1kg = 1000g [To convert a larger unit (kg) to a smaller unit (g) we multiply by the conversion factor.]

Therefore, 4 kg = 4 $\times$ 1000 g

Now, 4000g - 400g = 3600 g
