Answer:
The percent of 9 girls is 30%
Explanation:
To find the percentage of a number from a total divide the number by the total and then multiply the quotient by 100%
∵ There are 19 girls
∵ The total of the students is 30
- You need to find the percentage of 9 girls from the students,
that means the number is 9 and the total is 30
∵ You need to find the percent of 9 girls
∴ The percent =
× 100%
∵
![(9)/(30)=(3)/(10)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/fq0d95k1ldnrwibnrgnhnq9dw69g3zbhyb.png)
∵
![(3)/(10)=0.3](https://img.qammunity.org/2021/formulas/mathematics/middle-school/2juwu31me3zalvc9jcjh429z6cjzkweeb8.png)
∴ The percent = 0.3 × 100%
∴ The percent = 30%
∴ The percent of 9 girls is 30%
