Question

# There are two packs of cereal in the kitchen. One pack has 450 g of weight and the other has 1.67 kg. Total weight of the cereal in terms of kg is ______________.

Hint:

## The correct answer is: 2.12

### The given weights of the cereal packs are 450 g and 1.67 kg.We have to find the total weight. To find the total weight, we will have to add the quantities. But to add the quantities, their units must be the same. So we will have to convert the units. We are asked to find the weight in kg.The weight of the first quantity is in grams. So we will convert it into kg. And the weight of the second quantity is in kg, so we will keep it as it is.To convert grams into kilograms, we should take the relation between them.The relation between them is1 kilogram = 1000 gramsSo, if we want to find the value of 1 gram,We will have to divide both the sides by 1000.1 gram = 1/ 1000= 0.001 kgTo convert 450 grams into kilograms, we will multiply by the number 0.001.450 grams = 450 × 0.001 kg= 0.45 kgNow we have the weight of the first cereal in kg.To find the total weight, we will add the weight of the two packs.Total weight = weight of first pack + weight of second pack= 0.45 + 1.67= 2.12 kgSo the total weight of the packs of cereals is 2.12 kg.

For such questions, we should know the conversions of units.
