Question

chauncy had 5 dekagrams of cocoa to make brownies. each batch of brownies required 1 decigram of cocoa. how many batches of brownies could chauncy make? if one batch served 20 people, how many people could chauncy serve?

Answer 1

1 decameter is equal to 100 decimeter. So chauncy has 500 decigrams of cocoa (100 × 5). No. Of ppl chauncy can serve is equal to 500 × 20 =10000.

Answer 2

cocoa chauncy has= 5decagrams = 5*100 decigrams = 500 decigrams
1 batch of brownies requires 1 decigram of cocoa
therefore chaucy can make 500*1=500 batches of brownies
1 batch of brownies serves 20 ppl 
therefore 500 batches serves 500*20 ppl = 10,000 ppl
