Because the ratio is eight to one and 147 child tickets were sold, an easy way to solve the problem is through cross-multiplication: 8 over 1 times 147 over X. Using this equation, you'd divide 147, the number of child tickets, by 8, the child ticket ratio equivelant. By doing this, you'll find that the adult tickets sold on Saturday was approximately 18 (the answer comes out to a decimal, but for tickets you'd round to the nearest number).
