Maura needs a total of 2 1/4 hours to finish reading a book yesterday she read for one and 7/8 hours supply the correct numbers to complete the equation that can be used to determine the number of hours H that more needs to finish the book

To determine the number of hours Maura needs to finish the book, we can subtract the time she has already spent reading from the total time she needs.

Total time needed: 2 1/4 hours
Time already spent: 1 7/8 hours

Let's convert both fractions to the same denominator:

2 1/4 hours = 9/4 hours
1 7/8 hours = 15/8 hours

Now we can subtract the time already spent from the total time needed:

H = (total time needed) - (time already spent)
H = 9/4 - 15/8

To subtract fractions, the denominators must be the same. Since 4 is equivalent to 8 multiplied by 2, we can rewrite the equation as:

H = 9/4 - 15/8
H = 9/4 - 15/8
H = 9/4 - (15/8 * 2/2)
H = 9/4 - 30/16
H = (9*4)/(4*4) - 30/16
H = 36/16 - 30/16
H = 6/16

The equation to determine the number of hours Maura needs to finish the book is:

H = 6/16 or H = 3/8
