Question

A bucket of nails contains 4.20 × 102 nails. how many dozens of nails does the bucket contain? 1 dozen=12 objects

Answer 1

First, you must multiply 4.20 x 102 to get the total number of nails in the bucket. 4.20 x 102= 504 nails. Then, to get the amount of nails in dozens, you must divide the number by 12 because there are 12 objects in 1 dozen. 504 nails/12= 42. Therefore, there are 42 dozen nails in the bucket.
