Explanation:

Let 12% of x is 240 gm.

Therefore,

12 \% \:  \times x = 240 \\  \frac{12}{100}  \times x = 240 \\ x =  \frac{240 \times 100}{12}  = 2000 \:= 2 kg

Answer:

12% of 2 kg weight is 240 gm

Explanation:

Given:

Let 12% of w is 240 gm.  

Assume the unknown weight as w,

Therefore,  

12%×w=240 ;

Substitute % by 100 to the above equation;

\frac{12}{100} \times w =240 ; -------A

We need to find the value of w,so move \frac{12}{100} to RHS,while moving \frac{12}{100} will become reciprocal as \frac{100}{12}

So,W= \frac{240 \times 100}{12} =2000;

We need to convert gram to kg;

1 gram=0.001 kg;

0.001 can be written as 1/1000kg;

Therefor 1 gram =1/1000kg;

Substitute the above value to the given equation A,

W= \frac{2000}{1000} =2kg
