1. Count the states: There are 50 states in the US.
2. Count the states starting with vowels: These are Alaska, Arkansas, Iowa, Ohio, and Utah (5 states).
3. Subtract to find the consonant states: 50 total states - 5 vowel states = 45 consonant states.
4. Express as a fraction: 45 consonant states / 50 total states = 9/10
Therefore, 9/10 of the states in the US begin with a consonant.
