Final answer:
To find out how many grams of modeling clay each of the 9 students gets, we convert 4.5 kg to grams (4500 grams) and then divide by 9, which results in 500 grams per student.
Step-by-step explanation:
To divide a box of modeling clay with a mass of 4.5 kg equally among 9 students, we first convert the mass to grams. We know that 1 kilogram equals 1000 grams, so we multiply 4.5 kg by 1000 to get 4500 grams. Next, we divide 4500 grams by 9 to determine the amount of clay each student would get.
Step-by-step calculation:
- Convert kilograms to grams: 4.5 kg × 1000 = 4500 grams.
- Divide the total grams by the number of students: 4500 grams ÷ 9 = 500 grams per student.
