If 64 ⋅ 789 = 50,496, what is 6.4 × 7.89? (1 point)
To determine the product of 6.4 and 7.89, we need to move the decimal point one place to the left for both numbers. Thus, 6.4 becomes 0.64 and 7.89 becomes 0.789. Hence, 0.64 × 0.789 is equivalent to 64 ⋅ 789, which is 50,496. Therefore, 6.4 × 7.89 is also equal to 50,496.
To find the product of 6.4 × 7.89, follow these steps:
Step 1: Move the decimal point one place to the left in each number to remove the decimal.
6.4 becomes 64.
7.89 becomes 789.
Step 2: Multiply the two numbers without the decimals.
64 × 789 = 50,496.
Step 3: Place the decimal point back in the result.
50,496 becomes 5,049.6.
Therefore, 6.4 × 7.89 equals 5,049.6.
