Sagot :

Answer:

52% of the grid is shaded. You would need 7 more squares in order to get 80%.

Step-by-step explanation:

There are 25 boxes. You want to figure out how much each box is worth.

So,

You divide 100 by 25. You will get an answer of 4.

So now you know how much each box is worth.

There are 13 boxes shaded in, so you multiply 13 by 4 to get 52.

Keep adding boxes in order to get 80%. For example, 52%, 56%, 60%, until you get to 80%. Then see how many boxes you added up to get 80%.

We would need 7 more squares in order to get 80%. Thus, 52% of the grid is shaded.
