Answer 2

Answer:

Given that 240 gm of 4 kg

We have to express this in percentage

But we know that 1 kg = 1000 gm

Let us first convert 4 kg to gm

4 kg = 4 x 1000 gm = 4000 gm

The formula of "a" % of "b" is given as:

percentage = \frac{a}{b} \times 100percentage=

b

a

×100

Hence 240 gm as percentage of 4000 gm is given as:

\begin{gathered}= \frac{240}{4000} \times 100\\\\= \frac{24}{4} = 6\end{gathered}

=

4000

240

×100

=

4

24

=6

Thus the answer is 6%
