The number 1.693 rounded to the nearest tenth is 1.7.
Rounding a number involves approximating it to a specified place value. In this case, we are rounding to the nearest tenth, which means we want one decimal place. The tenths place is the first digit after the decimal point. For the given number 1.693, the digit in the tenths place is 9. Since 9 is equal to or greater than 5, we round up the digit in the tenths place. Therefore, 1.693 rounded to the nearest tenth is 1.7.
When rounding, it's important to understand the digit's value in the place we are rounding to. If the digit is 5 or greater, we round up; if it's less than 5, we round down. This process helps simplify numbers for easier understanding or presentation. In the case of 1.693, rounding to the nearest tenth gives us a clear and concise representation of the number while preserving a reasonable level of accuracy.
