What do you know so far?
It’s okay if you aren’t sure of the answers to these questions because soon you’ll watch a video about pirate-themed mini golf that will help you learn all about ratios and unit rates.
Then after you do some practice problems, you’ll take another short quiz so you can compare how you did against where you started.

1
What is a ratio?
a
Two numbers added together to find a total
b
A figure resulting from a transformation
c
A comparison of two quantities by division
d
A number greater than zero

Let’s take a trip to a local mini-golf course, where the golf clubs are decorated with animal stickers. The owner is fascinated by dinosaurs. For every two stickers of a puppy, there are five stickers of a dinosaur. How could this comparison be correctly formatted as a ratio?
a
:2 to :5
b
2:5
c
2 under 5
d
2 < 5

The table shows how many of each type of supply is left at the end of a busy day at the mini-golf course. What is the ratio of golf balls to clubs left?
Heads up! In mini-golf, there are usually 18 “holes,” or places where each player swings a golf club to try to get a ball into a hole in the ground. Each hole is decorated with something fun, like a castle. Careful, you don’t want to swing and have your ball roll right by the hole!

You notice it takes 60 minutes to play 10 holes at the mini-golf course. At that rate, how many minutes does it take to play one hole on average?

The mini-golf course also sells souvenir golf balls printed with fun graphics. The golf ball with sharks on it is a customer favorite. The shop sells 140 of these each week (seven days). On average, what is the unit rate of how many are sold per day?
a
140:7 per day
b
140/7 = 20 per day
c
7/140 = 0.05 per day
d
140*7 = 980 per day
