Answer:

350 students

Step-by-step explanation:

Let x be the number of students at the schoool. This number of students form 100%. Since 210 students (60%) of the sixth-grade students said that hip-hop is their favorite kind of music, then

x students - 100%,

210 students - 60%.

Mathematically, you can write a proportion:

[tex]\dfrac{x}{210}=\dfrac{100}{60}\Rightarrow 60\cdot x=100\cdot 210,\\ \\x=\dfrac{21,000}{60}=350.[/tex]
