Problem 2: How many coffee cups are required to hold

4,500 drops?

1 drop (gtt) = 1 minim

1 teaspoon (t) = 60 drops (gtt)

1 teaspoon (t) = 5 milliliters (mL)

1 tablespoon (T) = 3 teaspoons (t)

1 ounce (oz) = 2 tablespoons (T)

1 coffee cup (c) = 8 ounces (oz)

1 medium sized glass = 8 ounces (oz)

1 measuring cup = 8 ounces (oz)

And finally, ounces to coffee cups.

4500 drp

60 drp

1 t

3 t

1 T

1 oz

2 T

1 cup

= 1.5625 cups

8 oz

Would we ever encounter a problem like this on the job?

Probably not. But it’s a good exercise in showing how ratios

can be linked to make a conversion.
