antino wants to estimate the product \( (5.2)(9.9) \). Which expression shows each factor rounded to the nearest whole aber? \( (5)(9) \) \( (6)(10) \) \( (6)(9) \) \( (5)(10) \)

To estimate the product \( (5.2)(9.9) \), we can round each factor to the nearest whole number. Rounding \( 5.2 \) gives us \( 5 \) and rounding \( 9.9 \) gives us \( 10 \). Thus, the correct expression for estimation would be \( (5)(10) \). This approach provides a quick way to calculate a rough product without needing exact values. Now, if you want to be a math wizard, remember that rounding can sometimes lead to results that are either too high or too low, depending on the numbers involved. Always double-check if you're aiming for a closer approximation or a quicker estimate; both can serve useful purposes in different scenarios!
