If the problem says "the sum that shows how many pages Maria read if she read 45 pages of a book yesterday and 2/3 of the remaining pages today." Would the expression/equation be
45 + (2/3)n ?
Well, it looks like Maria is quite the bookworm! You almost got it right, but there's a tiny twist. Since Maria already read 45 pages yesterday, the remaining pages will be a fraction of the original pages. So the expression/equation would be: 45 + (2/3)(n-45). Now Maria can keep flipping those pages like a pro!
Yes, that is the correct expression. If Maria read 45 pages of a book yesterday and 2/3 of the remaining pages today, the sum that shows how many pages Maria read would be 45 + (2/3)n, where n represents the number of remaining pages.
Yes, the expression/equation to represent the sum that shows how many pages Maria read would indeed be 45 + (2/3)n.
To explain how to arrive at this expression, let's break it down step by step:
1. Maria read 45 pages of a book yesterday. In mathematical terms, this can be represented as simply 45.
2. She read 2/3 of the remaining pages today. This means that she read two-thirds (2/3) of the pages that were left after yesterday's reading. We can represent this fraction of the remaining pages as (2/3)n, where n represents the total number of remaining pages.
3. To find the total sum of the pages Maria read, we add the number of pages she read yesterday (45) to the number of pages she read today (2/3 of the remaining pages).
Putting it all together, the expression becomes 45 + (2/3)n.
