I do it by finding a common denominator.
For example, 2/3 - 1/5.
The least common denominator is 15. 2/3 = 10/15, and 1/5 = 3/15, the difference of which is 7/15.
Here is another example:
5/6 - 2/3. In this case, the least common denominator is 6.
2/3 = 4/6, and 5/6 - 4/6 = 1/6.
it stay the same when you subtract fractions and when you add fractions.
it is important to learn how to add and subtract fractions because we can use it when a time comes , when we have our own business and others .
Because to add fractions, the denominators must be equal.
you take away one of the whole number=then you add or subtract your fractions=
The same way you would add or subtract whole numbers, leaving the denominators alone.
it stay the same when you subtract fractions and when you add fractions.
Make the fractions equivalent then subtract
no, to add and subtract like and unlike fractions the denominator has to be the same,
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.
Numerators
Use the GCF to reduce fractions. Use the LCM to add and subtract unlike fractions. Carpenters work with fractions a lot.

Yes.
One may add, subtract, multiply and divide fractions once one has found the common denominator. Horse Isle Real Time Quiz Answer: common denominator
Because to add fractions, the denominators must be equal.
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
