What is the group of numbers?
500 - 125 = 375
72.50 × 6 = 435
435 - 375 = 60.
Divide the part (60) by the whole (500) then multiply by 100 to get the percent.
60 / 500 = .12
.12 × 100 = 12%
The correct answer is B
Complete Question
We have a total of 420 students. 2 times 3 times the number of girls is equal to 2 times the number of boys how many girls and how many boys
Answer:
The number of boys = x = 315 boys
The number of girls = y = 105 girls
Step-by-step explanation:
Let
The number of boys = x
The number of girls = y
We have 420 students
2 times 3 times the number of girls is equal to 2 times the number of boys
x + y = 420..... Equation 1
2 × 3y = 2x
6y => 2x
x => 6y/2 = 3y
We substitute 3y for x in Equation 1
3y + y = 420
4y = 420
y =>420/4
y => 105
Solving for x
x = 3y
x = 3 × 105
x = 315
Therefore,
The number of boys = x = 315 boys
The number of girls = y = 105 girls
Can you be more specific about what is P(5)? The probability would probably be around five though.
