Question

There is 0.3 kg of tin in a sword.
This is 15% of the total weight of the sword.
Calculate the total weight, in kg, of the sword.

pls help...

Answer 1

Answer: 2 kg

Step-by-step explanation: if 15% is 0.3kg in the sword, then 90% the sword is 1.8 kgs because 90%/15% = 6 x 0.3 kg = 1.8 kg. The remaining 10% is 2/3rds of 15% ( the only measurement we can use ) so now we have to divide 2/3 from 0.3 which is the value of 15%. That gives us with 0.2 kg. Now, we add both our answers to get 2 kg. So the weigh of the sword is 2 kg
