9 1/8 - 2 5/8

can you explain to me how 9 becomes 8 something?

9 1/8 - 2 5/8

Since you can't do 1/8-5/8 because you can't do 1-5, you have to "borrow"..
9 1/8 becomes 8 9/8...if it was just 9 it would be 8 8/8 because 8/8=1..so it's 8 9/8
8 9/8-2 5/8=?

8 + 1 = 9

1 = 8/8

8 8/8 = 9

To subtract mixed numbers like 9 1/8 and 2 5/8, you need to first convert them into improper fractions. Here's how we do that:

Step 1: Convert the whole numbers into fractions by multiplying them by the denominator of the fractions.
9 = 9 * 8/8 = 72/8
2 = 2 * 8/8 = 16/8

Step 2: Keep the denominators the same and subtract the numerators.
72/8 - 16/8 = (72 - 16)/8 = 56/8

Step 3: Simplify the resulting fraction, if possible.
56/8 can be simplified by dividing both the numerator and denominator by their common factor, which is 8.
56/8 = (56 ÷ 8) / (8 ÷ 8) = 7/1 = 7

So, the result of subtracting 2 5/8 from 9 1/8 is 7.
