Answer:
7
Step-by-step explanation:
After a number is taken out of the absolute value sign, it becomes positive. Therefore, |3| = 3, |-3| = 3, and |-1| = 1. Adding these up, we get 3 + 3 + 1 = 7
7*111 equals 777. Same rule applies as if it were 7*11, you just triple the number :)
It would be: 4 2/7 * 2 1/5
= 30/7 * 11/5
= 330/35
= 66/7
In short, Your Answer would be 66/7 or 9 3/7
