Question

A factory can make 3,848 pencils in one hour. Which is the best estimate of how many pencils can be made in 4 hours?

Answer 1

Approximately 16,000 pencils

Explanation:

Round 3,848 pencils to the nearest thousand.

That'll turn 3,848 to 4,000.

Since it's 4 hours:

4,000 * 4 = 16,000 pencils

Answer 2

15,392 pencils.

Explanation:

If a factory can make 3,848 pencils in an hour, then the factory can make 15,392 pencils in 4 hours.

Simply multiply 3,848 by 4.

`3,848*4=15,392`

Therefore, the factory can make 15,392 pencils in 4 hours.
