Mary needs a total of 2 1/4 hours to finish reading a book yesterday she had for one and 78 hours supply the correct numbers to complete the equation that can be used to determine the number of hours H that Mary needs to read to finish the book What is H plus blank equals blank
To find the number of hours H that Mary needs to read to finish the book, we can set up the equation:
H + 1 7/8 = 2 1/4
To combine the fractions on the right side, we need to have a common denominator, which is 8.
2 1/4 can be written as 9/4 in improper fraction form.
Now, we can rewrite the equation as:
H + 1 7/8 = 9/4
To get rid of the mixed number 1 7/8, we need to convert it to an improper fraction.
1 7/8 can be written as 15/8.
The equation now becomes:
H + 15/8 = 9/4
To solve for H, we need to isolate it on one side of the equation.
First, we can subtract 15/8 from both sides:
H + 15/8 - 15/8 = 9/4 - 15/8
This simplifies to:
H = -6/8
H can be further simplified as -3/4.
Therefore, H plus blank equals blank would be:
H + 0 = -3/4
