a piglet is to be fed with 500 g of highly nutritious feed a day. how many kilograms of feed are needed in 4 weeks for a dozen piglets? please answer with solution.

Sagot :

 ( 500g x 12 x 28 ) /2 = 42,000 kilograms for 4 weeks

explanation: 
how did I get 12 - Dozen means twelve
how did I get 28 - 1 week is equals to 7 days so, 4 weeks is equals to 28 days
how did I get 2 - In 1 kilogram there are 1000 grams so, 1000 grams divided by 500 grams (given) is equals to 2

( hope this helps... I think )
(500g x 28) /2 = 42, 000 kg
