Sue has 7/8 of her book left to read if she reads another 2/7 of the book, how much of the book will she have left?
1. 33/56
2. 1/5
3. 5/8
4. 23/40
How the hell is she even impatient? Also there is a chance she could just be using this to check her answers. .-.
To find out how much of the book Sue will have left after reading another 2/7 of the book, we first need to subtract 2/7 from 7/8.
Step 1: Find a common denominator for 7 and 8. The least common multiple of 7 and 8 is 56.
Step 2: Rewrite 7/8 and 2/7 with a denominator of 56.
7/8 = (7/8) * (7/7) = 49/56
2/7 = (2/7) * (8/8) = 16/56
Step 3: Subtract 16/56 from 49/56.
49/56 - 16/56 = (49 - 16)/56 = 33/56
Therefore, Sue will have 33/56 of the book left to read. The answer is option 1.
To find out how much of the book Sue will have left after reading another 2/7 of the book, we need to subtract 2/7 from 7/8.
First, let's find a common denominator for 7/8 and 2/7. The least common multiple of 8 and 7 is 56.
Now we can convert both fractions to have a denominator of 56:
7/8 = (7/8) * (7/7) = 49/56
2/7 = (2/7) * (8/8) = 16/56
Next, we subtract 16/56 from 49/56 to get:
49/56 - 16/56 = 33/56
Therefore, Sue will have 33/56 of the book left to read.
So, the correct answer is 1. 33/56.
geez, impatient much?
well, 7/8 - 2/7 = ?
