Final answer:
To find the total thickness of a stack of 15 magazines that are individually 2/11 inch thick, multiply the thickness of one magazine by the number of magazines, resulting in a combined thickness of 2 8/11 inches for the stack.
Step-by-step explanation:
The question asks us to determine the combined thickness of a stack of 15 magazines, where each magazine is 2/11 inch thick. To find the total thickness of 15 magazines stacked together, we can multiply the thickness of one magazine by the number of magazines.
Firstly, we calculate the total thickness:
Total thickness = Thickness of one magazine × Number of magazines
Thus, Total thickness = (2/11) inch × 15
We perform the multiplication:
Total thickness = 30/11 inch
Now, to express this as a mixed number, we divide 30 by 11:
Total thickness = 2 8/11 inches, which is the answer.
The stack of 15 magazines will be 2 8/11 inches thick.
