Here is your equation:
To subtract fractions, the denominator must be the same. The denominator is the bottom number in the fraction. The 2 denominators are 5 and 6. In order to make them the same, you have to find the LCM OF 5 and 6. To find it, list the multiples of both numbers and see which is common.
The LCM of 5 and 6 is 30. Now change the mixed numbers so that they have common denominators.
Here is your new equation:
Now you have a problem. You're subtracting a smaller fraction from a bigger fraction. That means you need to remove 1 from the whole number and add it to the fraction. Here's how:
Here is your new equation:
Subtract:
Since the denominator(top number) is a multiple of the numerator(top number), divide both numbers by the numerator.
