9- 1 2/8= I got 8 1/4 but the teacher took 2 points off I don't know what I did wrong?
9 = 8 8/8
8 8/8 - 1 2/8 = 7 6/8 = 7 3/4
Thank you Ms. Sue
You're welcome, Jared.
To find the difference between 9 and 1 2/8, we need to subtract the two numbers. Let's break it down step by step:
1. First, convert the mixed number 1 2/8 into an improper fraction. To do this, multiply the whole number (1) by the denominator of the fraction (8), then add the numerator (2). This gives us (1 * 8) + 2 = 10.
So, 1 2/8 can be written as an improper fraction: 10/8.
2. Now that we have both terms as fractions, we subtract the second fraction from the first:
9 - 10/8.
To subtract fractions, both fractions need to have a common denominator. In this case, the denominator is already the same (8), so we can move on to the subtraction.
3. To subtract the fractions, subtract the numerator of the second fraction from the numerator of the first fraction, while keeping the denominator the same:
9 - 10/8 = (9 * 8 - 10) / 8 = (72 - 10) / 8 = 62 / 8.
At this point, we have 62/8 as the answer. However, we can simplify the fraction further:
4. Divide both the numerator and denominator by their greatest common divisor (GCD) to simplify the fraction:
The GCD of 62 and 8 is 2. Divide both numbers by 2:
62 / 2 = 31, and 8 / 2 = 4.
So, the final simplified answer is:
62/8 = 31/4.
Therefore, the correct answer to 9 - 1 2/8 is 31/4 or 7 3/4.
If your teacher deducted points and you're not sure what you did wrong, carefully review the steps explained above to make sure you followed them correctly. Double-check your calculations and pay attention to any possible mistakes in the conversion, subtraction, or simplification processes.
