To calculate the relative frequency of landing on number 1, you divide the frequency of number 1 by the total number of spins.
The frequency of number 1 is 12, and the total number of spins is 100.
Relative frequency for number 1 = Frequency of number 1 / Total number of spins Relative frequency for number 1 = 12 / 100
Now, simplify the fraction: Relative frequency for number 1 = 12/100 = 3/25
