how do you subtract whole numbers into fractions?
I don't understand your question. Please post a couple of examples.
2-3/5
3-3/6
For the second, convert 3/6 to 1/2. I'd it's confusing, Make 1/2 to a decimal. = .5 or .50. Subtract 3 and .5 and you will get .2.5. Which equals to 2 1/2. Fr the first, convert w/5
Change the whole number to a whole number and fraction with the same denominator.
2 - 3/5 = 2 = 1 5/5
1 5/5 - 3/5 = 1 2/5
3 - 3/6 = 2 6/6 - 3/6 = 2 3/6
This site has an excellent explanation.

To subtract whole numbers into fractions, you need to convert the whole numbers into fractions first. Here's how you can do it:
Step 1: Write the whole number as a fraction. To do this, put the whole number over the denominator 1. For example, if you have the whole number 3, you can write it as 3/1.
Step 2: Find a common denominator for the fractions you want to subtract. If the fractions already share a common denominator, you can skip this step. Otherwise, you need to find the least common multiple (LCM) of the denominators.
Step 3: Convert the fractions to have the same denominator. To do this, multiply the numerator and denominator of each fraction by the same number so that all fractions have the common denominator found in Step 2.
Step 4: Subtract the numerators of the fractions. Keep the common denominator.
Step 5: Simplify the resulting fraction, if necessary. You can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).
Let's look at an example:
Example: Subtract 3 from 7/5.
Step 1: Write 3 as a fraction: 3/1.
Step 2: The denominators are already different, so we need to find the LCM of 1 and 5, which is 5.
Step 3: Convert 3/1 to have a denominator of 5: (3/1) x (5/5) = 15/5.
Step 4: Subtract the numerators: (7/5) - (15/5) = (7 - 15)/5 = (-8)/5.
Step 5: The resulting fraction -8/5 is already in its simplest form.
So, subtracting 3 from 7/5 gives you -8/5.
