Question

A cleaner recommends mixing 1½ cup of cleaner for every 12 cups of water. What is the ratio of cleaner to water in simplest form?

Answer 1

we know that

1½ cup of cleaner-------> (1*2+1)/2-----> 3/2 cup of cleaner

the ratio of cleaner to water=(3/2)/12---> 3/(2*12)--> 3/24--> 1/8

the answer is
1/8
