Math ratio word problem
posted by Rachal on .
The ratio of horseshoes to shamrocks was 11 to 5, and two times the number of shamrocks was 12 less than the number of horseshoes. How many were shamrocks?
thank you :)

Rachal, I messed that up.
H/S=11/5 so 5H=11S
and 2S+12=H
From the first equation H=11S/5
putting that into the second.
2S+12=11S/5
multiplying both sides by 5
10S+60=11S
adding sixty to both sides and subtracting 11S from both sides.
S=60 or S=60
so H=11*60/5=132 
can someone make up 5 ratio road problems?
