blagie [28]

Answer:

Hi there!

Your answer is: 150 people prefer that school assemblies be held on Friday afternoon

Step-by-step explanation:

3 out of 4 students means that 75% of students prefer assemblies on Friday afternoon!

To find 75% of 200:

200 = 100%

/100 to find 1%

2 people = 1%

Multiply it by 75 to determine 75%

2×75= 150

150people is 75% of 200 people!

I hope this makes sense! Let me know if you have questions!
