Question

what number round to 9.4 when rounded to the nearest tenth? A. 9.38 and 9.45 B. 9.37 and 9.42 C. 9.39 and 9.47 D. 9.41 and 9.52.

Answer 1

To round a number to the nearest tenth we have to look at the second digit after the decimal point.

If it is greater than 5 we have to add 1 unit to the place of the tenths, if not it remains the same.

B. 9.37 and 9.42

9.37, the second digit after the decimal point is 7.

7>5, so we have to add 1 to the tenths.

9.4

9.42. the second digit after the decimal point is 2.

2<5

The tenths place remains the same:

9.4
