سؤال 29

Which calculation does NOT round directly to the stated place?

5.284 to one decimal place gives 5.3.
7.632 to two decimal places gives 7.63.
9.76 to one decimal place gives 9.8.
4.449 to one decimal place gives 4.5.پاسخ درست

توضیح

Direct rounding gives 5.284 to tenths as 5.3, 7.632 to hundredths as 7.63, and 9.76 to tenths as 9.8. Changing 4.449 to 4.5 at one decimal place uses the later 9 after first making 4.45, but the deciding hundredths digit is 4, so direct rounding gives 4.4.
