Question

60 out of the 80 students at a school assembly were first - grade students. what percentage of the students at the assembly were first - graders? write your answer using a percent sign (%).

Explanation:

Step1: Use the percentage formula

The formula for percentage is $\frac{\text{part}}{\text{whole}}\times100\%$. Here, the part is the number of first - graders ($60$) and the whole is the total number of students ($80$).

Step2: Substitute the values into the formula

Substitute $60$ for the part and $80$ for the whole: $\frac{60}{80}\times100\%$.

Step3: Simplify the fraction

$\frac{60}{80}=\frac{3}{4}$. Then $\frac{3}{4}\times100\% = 75\%$.

Answer:

$75\%$
