Answer

Los números que redondean a 800 al aproximarse al centenar son aquellos que están entre 750 y 849.

Solution

1. Primero, recordamos que para redondear al centenar más cercano debemos fijarnos en el dígito de las decenas. 2. Un número se redondeará a \(800\) si está más cerca de \(800\) que de \(700\) u \(900\). 3. La regla general es que si un número se encuentra entre \(750\) y \(849\) (incluyendo \(750\) pero no \(850\)), al redondear al centenar dará como resultado \(800\). Esto se debe a que: - Los números menores que \(750\) se redondean hacia abajo a \(700\). - Los números de \(750\) hasta \(849\) se redondean hacia \(800\). - A partir de \(850\), se redondea a \(900\). 4. Por lo tanto, entre las opciones propuestas, se deben seleccionar aquellos números que pertenezcan al intervalo: \[ 750 \leq n < 850 \] 5. Cualquier número que cumpla esta condición al redondear al centenar dará como resultado \(800\).

To round numbers to the nearest hundred, you need to look at the tens digit. If it's 5 or more, you round up; if it's 4 or less, you round down. Therefore, any number from 750 to 849 will round to 800. So, for example, numbers like 750, 765, 800, and 845 all qualify. Got your pencils ready? Let's round some numbers! Now, remember that rounding is a useful skill, especially in everyday scenarios like shopping or budgeting. Suppose you're checking your bank account and see a balance of $785. By rounding it to the nearest hundred, you can quickly estimate that you have about $800 in your account—very handy for quick mental math!
