Answer
Answer:
D. 123.76
Explanation:
Step1: Recall sign - rule for multiplication
The product of two negative numbers is positive. So, ((-22.1)(-5.6)=22.1\times5.6).
Step2: Perform the multiplication
(22.1\times5.6=(22 + 0.1)\times5.6=22\times5.6+0.1\times5.6). (22\times5.6 = 22\times(5 + 0.6)=22\times5+22\times0.6=110 + 13.2 = 123.2). (0.1\times5.6 = 0.56). (123.2+0.56 = 123.76).
