Answer:
0.007 kg
Explanation:
There are 25 packets
Each packet contains 4 biscuits.
The total number of biscuits = 4 * 25
The total number of biscuits = 100
100 biscuits = 0.7 kg
1 biscuit is 0.7 kg / 100
1 biscuit is 0.007 kg
If you are not sure of this, put it in a calculator.
Just out of curiosity note that 1 kg = 1000 grams
0.007 kg = 0.007 * 1000 = 7 grams each.
use 0.007 as your answer.
