Make sure you give the simplest form of the ratio for every movie, then compare them.

Movie B, 1:1

Practice makes perfect
A ratio is a comparison of two quantities by division. We can write a ratio of two numbers a and b, where b ≠ 0, in three ways. a/b a : b a to b We usually express a and b in the same unit and write the ratio in simplest form. We are given the following measurements.
Movie Number of Academy Awards Number of nominations
Movie A 2 4
Movie B 11 11
Movie C 11 14
Movie D 8 12

We want to find the greatest ratio of Academy Awards to nominations. Let's write down and simplify our ratios.

Movie Ratio Simplified ratio Ratio as a number
Movie A 2:4 1:2 0.5
Movie B 11:11 1:1 1
Movie C 11:14 11:14 ≈ 0.79
Movie D 8:12 2:3 ≈ 0.67

Therefore, Movie B has the greatest ratio of Academy Awards to nominations. We can write this simplified ratio in any of the three ways. 1/1 1:1 1to1
