Answer: 90Step-by-step explanation:When rounding off a number, you first look at the digit right after the place value you want to round to. If that digit is 5 or higher, you increase the rounding digit by one. But if it’s 4 or lower, you keep the rounding digit the same. After rounding, you either change the following digits to zeros (for whole numbers) or simply drop them (for decimals). Example, we want to round 94 to the nearest ten. First, we look at the digit in the ones place, which is 4. Since 4 is less than 5, we do not change the tens digit. So, we keep the 9 and change the 4 to 0.
