Explanation Given Information: The multiplication of: 378 × 72 _ . Formula used: The procedure used to multiply two whole numbers is: Step 1: Find the estimated product of the rounded numbers with each number rounded to its first digit. Step 2: Use the calculator to calculate the exact product of the numbers. Step 3: Compare the estimated and exact product to determine if the exact product is reasonable. Step 4: Multiply the numbers manually to verify the product. Calculation: Consider the multiplication of: 378 × 72 _ Now, round each number to its first digit. 378 → 400 × 72 _ → × 70 _ So, the estimated product is calculated as, 400 × 70 _ 28 , 000 Thus, the estimated product is obtained as 28 , 000 . Now, find the exact product of the numbers by calculator. Enter the provided numbers into the calculator. So, the exact product is obtained as, 378 × 72 = ⇒ 27 , 216 The obtained estimated product and the exact product are not reasonably close. Verify the exact product by multiplying the numbers manually
