That's the Distributive Property
You multiply whatever is outside of the parenthesis with everything in the parenthesis. That's why when you multiply a with everything in the parenthesis (b + c), it becomes a*b + a*c.
180 of 72% is 129.6. 180*72= 12960. Since 72% = .72, you need to put the decimal 2 places behind the decimal.
12 inches = 1 foot
11664/12 = 972 feet²

_ - _ This problem is a no go bc the denominators aren't the same.
6 5
First you will need to find the common denominator. <em>It is 30</em>.
Next you will divide 30 by 6 and get 5. Now you know what to multiply the numerator by.
So, 6*5 is 30. 30 will now be your denominator. 5*5 is 25. 25 will be your numerator.
After you have done that you will move onto the fraction 2/5.
First, you will remember your common denominator, 30.
You will use that, and divide 30 by 5 and get 6. You now know what to multiply you numerator by. 2*6 is 12.
Your new problem looks like:
25 12 13
_ - _ _
30 30 30
