Question

what percent of the boxes have x's in them

Answer 1

It is a 4 by 8 grid.  So there are 32 squares total.
Now,  count how many x's are on the boxes.
I counted 14 x'ed boxes.
Divide 14 by 32
14/32=0.4375
Now convert to a percent.  Move the decimal two places to the left.
You get 43.75% as the answer.

Answer 2

There are 32 total boxes. Only 14 of the boxes in the grid have an x inside of the box. We can find what percent of the boxes have an x in them by making a fraction. $\frac{14}{32}$ represents the number of boxes that have an x in them out of all the boxes in the grid.

$\frac{14}{32}$ can be reduced to $\frac{7}{16}$ by dividing both the numerator and denominator by the Greatest Common Factor of 14 and 32 which is 2.

7 ÷ 16 = 0.4375

0.4375 × 100 = 43.75%

Therefore, 43.75% of the boxes have an x inside of them.
