Round 7.845 to the nearest tenth.

Explanation:
Rounding to the nearest tenth means keeping one digit after the decimal and deciding whether to leave it or increase it based on the next digit. You look at the hundredths place to decide. If the hundredths digit is 5 or higher, you raise the tenths digit by 1; if it's lower than 5, you keep the tenths digit as is. For 7.845, the tenths digit is 8 and the hundredths digit is 4, which is less than 5, so you don’t change the 8. The thousandths place won’t affect this rounding to the tenth. The result is 7.8.
