subtracting fractions
In fractions, you can NEVER add or subtract
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
it stay the same when you subtract fractions and when you add fractions.
Make the fractions equivalent then subtract
Subtract as if there were no denominators.
multiply the fractions until they have common denominators and then subtract them
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Because think of like fractions as the same things.. you can subtract halves from halves for example, but what does it mean to take away a half from a third?By converting them into like fractions, we can add or subtract them easily.
You need a common denominator in order to add or subtract fractions.
Once you find the LCD, convert the fractions to their equivalents and then you can add and/or subtract them correctly.
