Draw arrays showing two different ways that Demarcus could use the multiplication facts he already knows to determine $4^{*} 7$. In each case, write an equation that corresponds to the array and that shows how $4^{*} 7$ is related to other multiplication facts.

Step 1 ：Draw arrays showing two different ways that Demarcus could use the multiplication facts he already knows to determine $4^{*} 7$. In each case, write an equation that corresponds to the array and that shows how $4^{*} 7$ is related to other multiplication facts.

Step 2 ：The multiplication of 4 and 7 can be represented in two ways. First, it can be represented as the sum of the multiplication of 2 and 7 twice, which is \(2*7 + 2*7 = 28\).

Step 3 ：Second, it can be represented as the sum of the multiplication of 4 and 4 and the multiplication of 4 and 3, which is \(4*4 + 4*3 = 28\).

Step 4 ：Both methods give the same result, which is \(\boxed{28}\).
