Question

At a school, 60% of the sixth-grade students said that pizza is their favorite kind food. If 210 sixth-grade students prefer pizza, how many sixth-grade students are at the school?

Answer 1

Answer:

350

Step-by-step explanation:

Let $s=$ total number of sixth-grade students.

It is given that 60% of sixth-grade students prefer pizza which is equivalent to 210 sixth-grade students. With this, the following can be written:

$60\%s = 210$

$0.6s=210$ ($60\%$ can be converted into the decimal form $0.6$)

$s = 210\div 0.6$

$=350$

∴ There is a total of 350 sixth-grade students in the school.

Hope this helps :)
