If you were to divide 2.1 by 1.488 you would get a answer such as 1.41129....
If the number is above 5, you round to the next highest number.
If the number is 4 and below, you don’t round to the next highest number.
Since 1.41 has a number below 4 that you have to round, the nearest tenth would stay 4.
meaning the answer is 1.4
