Explanation:
Let's look at the problem:
According to PEMDAS or the Order of Operations, we need to solve the problem in the parentheses,
First, we need to make the denominators the same. Since 18 is a multiple of 6, we just need to change
Now, let's plug
Or,
Thus, the problem is :
Here, we need to do
Now let's solve,
Since the top and bottom of
Now, the last step is to do
Finally, the last step is to add:
Then simplify:
So
Explanation:
Given:
Multiply and divide have priority over add or subtract but remembering that brackets group things
Consider
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This this is the same as:
5 will divide exactly into any number ending in 5 or 0. So we need to multiply the 18 until we have a 0 as the last digit.
