Chad completed 75% of a book when he read the first 180 pages. How many pages are in the book?

240

Step-by-step explanation:

If 75% is 180, we need to find the remaining 25%.

Obviously, 25 is 1/3 of 75 (and "of" is another word for times) meaning that to find 25%, multiply 75% by 1/3.

Since 75% = 180, we do:

180 x 1/3

60

Now add these two values together to get:

180 + 60 = 240

The answer is 240

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
