Answer: S=25


Step-by-step explanation:

Given: Total creepy-crawly creatures in a room=20

Also, there are 20 % are spiders.

Since 20%=0.2

The number of spiders=\(0.2\times20=4\)

Then number of flies= 20-4=16

Since flies has 6 legs, then the number of legs in all flies=\(6\times16=96\)

Also, spider has 8 legs, then the number of all legs in spiders= \(8\times4=32\)

Total legs of all creepy crawls= 96+32=128

The percent of spider legs=\(\frac{32}{128}\times100=25\%\)

hence, if S% of the total legs belong to spiders, then S=25
