Question

Ms. Lackey gave each student in her class a calculator.Each calculator weighed 16 ounces. If Ms.Lackey gave each of her 20 students a calculator,how many pounds did the calculators weigh in all?

Answer 1

Everyone got a calculator.....each weighed 16 oz.......gave them to 20 students.....20 * 16 = 320 total oz

16 oz = 1 lb

320/16 = 20 lbs <==

or, if u just think about it...u gave 16 oz to each student.....16 oz = 1 lb...so u gave 1 lb to each student....20 students = 20 lbs
