Question

Find the weight in grams of the contents of a breakfast cereal package if the gross weight is 1kg 200g and the packaging weighs 15g.

Answer 1

Hint: Gross weight is the total weight of the package i.e. gross weight=weight of contents + weight of packaging. In this question, gross weight and packaging weight is given. So, using basic calculations of multiplications, addition and subtraction will give us the required answer. Also we need to remember, 1kg = 1000g

Formula used:
Gross weight=Weight of contents + Weight of packaging.

Complete step by step answer:
Given that Gross weight $= 1kg\, 200g$
First, we will convert all weights into the same units i.e. in grams.
Since $1kg = 1000g $
So, Gross weight$ =1 \times 1000g + 200 g$
$=1200 g$
And also given that Weight of packaging $=15 g$
By definition of gross weight, we have, Gross weight=Weight of contents + Weight of packaging.
So, Weight of contents = Gross weight - Weight of packaging
$=1200 – 15$
$=1185 g$

$\therefore$ The weight in grams of the contents of a breakfast cereal package is 1185g.

Note:
For such types of questions you need to know the definitions of different terms used in the question. And also how to convert one unit to some other unit. Different units of weight are
$ 1 kg = 1000g$; $1$ hectogram = $100$ gram; $1$ decagram = $10$ gram
