Jerry sold 7/20 of the total number of tickets that were sold for the spring band concert.
Total number of tickets sold =
![(7)/(20)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/alpdpttz70yjntqnvsp4necyuygeon1rer.png)
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.
= 35%
So 35% of the total number of tickets sold.
