Jerry sold 7/20 of the total number of tickets that were sold for the spring band concert.
Total number of tickets sold = [tex] \frac{7}{20} [/tex]
To find the percentage of the total number of tickets sold , we write 7/20 in percentage.
To convert 7/20 in to percentage we divide it to make it a decimal form and then multiply it by 100.
[tex] \frac{7}{20} = 0.35 * 100 [/tex] = 35%
So 35% of the total number of tickets sold.
