Answer:
92.5%
Step-by-step explanation:
shaded squares/total squares = 185/200
simplify:
(185/5)/(200/5) = 37/40
37/40= 35/40 + 2/40
32/40 + 5/40 = 4/5 + 1/8
4/5 + 1/8 = 0.8 + 0.125
0.8 + 0.125 = 80% + 12.5%
80% + 12.5% = 92.5%
Answer:

So, in this case:

The 8 and 3 numbers are easy to get from the graphic... and the order doesn't matter (8² + 3² = 3² + 8²).
That's an easy rule to remember.
I hope it helps.
