To round to the nearest tenth, look at the digit in the hundredths place (the second digit after the decimal point). If it is 5 or greater, round the tenths digit up by one. If it is 4 or less, keep the tenths digit the same and drop all remaining decimal digits.
The tenth place is the first digit immediately to the right of the decimal point. For example, in the number 21.75, the digit 7 is in the tenths place. Rounding to the nearest tenth means expressing the number with only one digit after the decimal point.
Yes. The hundredths digit is 8, which is 5 or greater, so you round the tenths digit (4) up by one to get 2.5.
0.89 rounded to the nearest tenth is 0.9. The hundredths digit is 9, which is 5 or greater, so the tenths digit rounds up from 8 to 9.
A 'ten' refers to the tens place, which is to the LEFT of the decimal point (e.g., the 2 in 23). A 'tenth' refers to the tenths place, which is to the RIGHT of the decimal point (e.g., the 3 in 2.38). They are completely different positions in the place value system.
By the standard rounding rule (round half up), a hundredths digit of exactly 5 causes the tenths digit to round up. For example, 3.25 rounds to 3.3. Some rounding modes (like round half to even) may behave differently, but the most common convention rounds up at exactly 5.
Yes. The same rule applies: look at the hundredths digit and round the tenths digit up or keep it the same. For example, -2.76 rounds to -2.8 because the hundredths digit (6) is 5 or greater, making the number more negative.
If your number already has exactly one decimal place, such as 4.7, it is already rounded to the nearest tenth. The calculator will return the same value since no rounding adjustment is needed.
