Rounding to the nearest 10th and rounding to the nearest hundred will not give a closer estimate of 748-431.
When rounding to the nearest 10th, we consider the digit in the hundredth place. In this case, the digit in the hundredth place is 4, which is less than 5. So, when rounding to the nearest 10th, we round down to 740.
When rounding to the nearest hundred, we consider the digit in the tens place. In this case, the digit in the tens place is 4, which is less than 5. So, when rounding to the nearest hundred, we also round down to 700.
Neither of these approximations (740 or 700) is closer to the actual value of 748-431, which is 317. So, rounding to the nearest 10th or the nearest hundred does not provide a closer estimate of the subtraction.
Will rounding to the nearest 10th or the nearest hundred give a closer estimate of 748-431?
