Explanation Given Information: A machine can produce 75 rolls in an hour. Formula used: Steps to multiply whole numbers. Step 1: Write the numbers in a vertical column, aligning digits according to their places. Step 2: For each place of the multiplier in turn, beginning with the ones place. (a) Multiply the multiplicand by the place digit of the multiplier. (b) Write the partial product directly below the multiplier, aligning the ones digit of the partial product with the place digit of the multiplier. Step 3: Add the partial products. Calculation: Consider the machine can produce 75 rolls in an hour and there are 24 hours in a day. Round each number to the first digit. Then 75 × 24 becomes 80 × 20 . Multiply the rounded numbers. Then, 80 × 20 = 1600 . So, the approximate value of 75 × 24 is 1600. Use a calculator to find the exact value of 75 × 24 . Open Ti-83 calculator and enter the expression, 75 × 24
