Explanation:
In the multiplication sentence –70 × 20 = –1,400, the integer 20 is the value that makes the equation true. When you multiply –70 by 20, you get –1,400 as the result. This demonstrates that multiplying a negative number (–70) by a positive number (20) results in a negative product (–1,400), which aligns with the rules of multiplication for integers. So, the integer 20 is the number you need to complete the equation correctly.
