Answer :
see so,1200 kg of coal=1kg of aluminum
if 1 soda can needs 15g of aliminium so
1200/15=80kg coal will be needed for 1 can of soda.
A ratio shows us the number of times a number contains another number. The amount of soda that is needed to produce one soda can is 18 kgs.
What is a Ratio?
A ratio shows us the number of times a number contains another number.
A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that it takes approximately 1200 KG of coal to produce the energy needed to make 1 kg of aluminium. Therefore, we can write the ratio of coal burned to the amount of aluminium produced as,
Amount of coal burned / Aluminium produced = 1200 kg/ 1kg
Since a single soda can requires 15 g of aluminium. Therefore, the amount of coal that will be needed to produce a soda can is,
Amount of coal burned / 0.015 kgs = 1200 kg/ 1kg
Amount of coal burned = (1200 × 0.015)/1
Amount of coal burned = 18 kg of coal
Hence, the amount of soda that is needed to produce one soda can is 18 kgs.
