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

350 6th grade students

Step-by-step explanation:

From the question

At a school, 60% of the sixth-grade students said that hip-hop is their favorite kind of music.

Total number of sixth graders that love hip-hop = 210

Let the total number of students in the school be represented as: x

Hence,

60% × x = 210

60/100 × x = 210

Cross Multiply

60x = 210 × 100

x = 210× 100/60

x = 350 students.

Therefore, the total number of sixth graders is 350 .

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
