Answer 3

1) 9 * 4 = 9 + 9 + 9 + 9 2) 9 * 7 = 9 + 9 + 9 + 9 + 9 + 9 + 9 9 * 7 = 70 + 7 9 * 4 = 9 + 3 + 9 9 * 7 = 9 + 8 + 9 9 * 4 = 9 + 5 + 9 9 * 7 = 9 + 6 + 9 9 * 4 = 20 + 16

Let's break it down:

1) To make 9 * 4 equal 9 + 9 + 9 + 9, we can split the number 9 into four equal parts: 9/4 = 2.25. So, the equation becomes 9 * 4 = 2.25 + 2.25 + 2.25 + 2.25, which is true.

2) To make 9 * 7 equal 9 + 9 + 9 + 9 + 9 + 9 + 9, we can split the number 9 into seven equal parts: 9/7 = 1.2857 (rounded to 4 decimal places). So, the equation becomes 9 * 7 = 1.2857 + 1.2857 + 1.2857 + 1.2857 + 1.2857 + 1.2857 + 1.2857. This equation is also true.

Additionally, we have the following equations: - 9 * 7 = 70 + 7, which is not true. The correct equation should be 9 * 7 = 63. - 9 * 4 = 9 + 3 + 9, which is not true. The correct equation should be 9 * 4 = 36. - 9 * 7 = 9 + 8 + 9, which is not true. The correct equation should be 9 * 7 = 63. - 9 * 4 = 9 + 5 + 9, which is not true. The correct equation should be 9 * 4 = 36. - 9 * 7 = 9 + 6 + 9, which is not true. The correct equation should be 9 * 7 = 63. - 9 * 4 = 20 + 16, which is not true. The correct equation should be 9 * 4 = 36.

It seems like there are several incorrect equations in the given statements. The correct equations for 9 * 7 and 9 * 4 are 9 * 7 = 63 and 9 * 4 = 36, respectively.
