Question

If 730g of pasta are added to 1.4kg. How much pasta is there now?

Answer 1

Hint: Now first we will convert 730g of pasta in kilograms. To do so we know that 1 kilogram is equal to 1000 grams. Now once we have converted 730g to kilogram we have both the quantities in kilogram and hence we will add to find the total weight of pasta.

Complete step-by-step answer:
Now let us first understand the concept of measurement. To quantify things we introduce the concept of measurements. Now to quantify how heavy the object is we have the measurement of weight. Weight is often used to measure food items, fruits etc.
The units of weight are kilograms denoted by kg and gram denoted by g.
We have 1kg = 1000g.
We are given that initially there was 1.4kg pasta.
Now to this pasta we add 730g of pasta.
Now we know that 1000g is 1kg.
Hence we can say that 1g is $\dfrac{1}{1000}kg$ .
Hence 730g is equal to $\dfrac{730}{1000}kg$
Hence we have 730g is 7.3kg.
Hence we can say that 7.3kg pasta was added to 1.4kg pasta.
Now the total pasta is equal to 7.3 + 1.4 = 8.7kg.
Hence now we have a total of 8.7kg pasta.

Note: Now note that when the two quantities given are in different units we must change the unit of one quantity such that in the end both the quantities are in same unit. Hence we can only add or subtract quantities with same units.
