Valentino wants to estimate the product (5.2)(9.9). Which expression shows each factor rounded to the nearest whole number?

Question

(5)(9)
(6)(10)
(6)(9)
(5)(10)

Answer 1

To estimate the product \( (5.2)(9.9) \), we round each factor to the nearest whole number.

• For \( 5.2 \), rounding to the nearest whole number gives \( 5 \).
• For \( 9.9 \), rounding to the nearest whole number gives \( 10 \).

Thus, the expression that shows each factor rounded to the nearest whole number is \( (5)(10) \).
