If I plan to run 400 yards and I have completed 80%, how many yards do I have left?
Dimas [21]

Answer:

You have 80 yards left to run.

Step-by-step explanation:

To solve this problem, we first must realize that if you have completed 80% of the run, that you have 20% left (this is because 100%-80% = 20%).  

Next, we must find 20% of 400 yards.  We must remember that in math, the word "of" represents multiplication.  We also know that 20% = 20/100 = 0.2.

To find 20% of 400 yards, we can perform the following operation:

20% * 400

0.2 * 400

80

Therefore, you have 80 yards left.

Hope this helps!
