The problem states that Moira needs a total of 2 1/3 hours to finish reading a book. To determine the number of hours, A, that Moira needs to read to finish the book, we need to subtract the time she already spent reading from the total time needed.
Let's first convert 2 1/3 hours to an improper fraction. To do this, we multiply the whole number (2) by the denominator of the fraction (3), and then add the numerator (1). This gives us (2 × 3) + 1 = 7. So, 2 1/3 hours can be written as 7/3 hours.
Now, let's denote the time Moira already spent reading as T/2 hours. We are given that "Yesterday, she read for 1 * T/2 hours". This means that T/2 hours is the time she spent yesterday.
To find the total time needed to finish the book, we need to subtract the time already spent from the total time needed.
Total time needed = Total time - Time already spent
Total time needed = 7/3 hours - T/2 hours
Thus, the equation to determine the number of hours, A, that Moira needs to read to finish the book is:
A = 7/3 - T/2
Moira needs a total of 2 1/3 hours to finish reading a book. Yesterday, she tead for 1 * T/2 hours. Supply the comect numbers to complete the equation frut can be used to determine the number of hours, A, that Maira needs to read to finish the book.
