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

Answer 1

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
