Final answer:
To find the number of days Frank walked to school, multiply the percentage (35%) by the total number of school days in a year (180).
Step-by-step explanation:
To find the number of days Frank walked to school, you can multiply the percentage of days he walked by the total number of school days in a year.
Using the given information, we know that Frank walked to school 35% of the time. Thus, the number of days he walked can be calculated by multiplying 35% by 180: 35% * 180 = 0.35 * 180 = 63.
Therefore, Frank walked to school for 63 days in a school year.
