Which gives the best estimate and the exact product of \( (5.9)(8.28) \) ? estimate: 40 ; exact product: 48.852 estimate: 48 ; exact product: 48.852 estimate: 400 ; exact product: 488.52 estimate: 480 ; exact product: 488.52

When estimating the product of \( (5.9)(8.28) \), rounding \( 5.9 \) to \( 6 \) and \( 8.28 \) to \( 8 \) gives us an estimate of \( 6 \times 8 = 48 \). The exact product, calculated as \( 5.9 \times 8.28 \), is approximately \( 48.852 \). Therefore, the best choice for an estimate and the exact product is: estimate: 48; exact product: 48.852. To make these calculations more fun, you can think of this as a mini-game! Rounding up can simplify mental math, and it helps you get in the ballpark. Just be sure to check your work with the exact numbers afterward—like solving a puzzle where you find the real picture after guessing the edge pieces!
