Question 3 • TN-Mathematical Reasoning for Decision Making (Supplement)
One dekagram equals 10 grams, and one gram equals 100 centigrams, so 1 dekagram = 1,000 centigrams. To convert 77 centigrams to dekagrams, divide by 1,000, which means moving the decimal point three places left: 77 centigrams = 0.077 dekagrams. So Marco should move the decimal left 3 places.
