Answer: ![55 \%](https://tex.z-dn.net/?f=55%20%5C%25)
Step-by-step explanation:
As we can see in the image below, the number of tiles that form the word HI!, is
; this represents the
or the total.
Now, if we count the number of tiles in H, this number will be
. So, we have to find what percent this number represents by a Rule of Three:
If:
----![100 \%](https://tex.z-dn.net/?f=100%20%5C%25)
----![?](https://tex.z-dn.net/?f=%3F)
Then:
![?=\frac{11}{20}(100)](https://tex.z-dn.net/?f=%3F%3D%5Cfrac%7B11%7D%7B20%7D%28100%29)
This is the percent of tiles in H.
