4 3/4 - 1 5/8
I got 3 1/8.
Here is my work:
4 3/4= 4 6/8
-1 5/8
3 1/8
Your work makes no sense to me, all I see is a bunch of numbers
I know what you are trying to say, but Math is a precise language and must be used as such. You have:
4 3/4= 4 6/8
-1 5/8
3 1/8
Should look like:
4 3/4 - 1 5/8
= 19/4 - 13/8 , getting rid of those useless mixed numbers
= 38/8 - 13/8 , common denominator
= 25/8

To subtract mixed numbers like 4 3/4 - 1 5/8, you need to convert the mixed numbers into improper fractions.
Firstly, let's convert 4 3/4 into an improper fraction:
4 * 4 = 16
16 + 3 = 19
The numerator of the improper fraction is 19.
The denominator remains the same, which is 4.
So, 4 3/4 as an improper fraction is 19/4.
Now let's convert 1 5/8 into an improper fraction:
1 * 8 = 8
8 + 5 = 13
The numerator of the improper fraction is 13.
The denominator remains the same, which is 8.
So, 1 5/8 as an improper fraction is 13/8.
Now, we can subtract the two improper fractions:
19/4 - 13/8
To subtract fractions, we need to have a common denominator.
The least common multiple (LCM) of 4 and 8 is 8.
To make the denominators the same, we multiply the numerator and denominator of the first fraction (19/4) by 2:
(19 * 2) / (4 * 2) = 38/8
So, the equation becomes:
38/8 - 13/8
Now that the denominators are the same, we can subtract the numerators:
38 - 13 = 25
Finally, we keep the denominator the same to get:
25/8
Therefore, 4 3/4 - 1 5/8 equals 25/8, or as a mixed number, it simplifies to 3 1/8.
