There were 2400 people at a concert.40%

of them were men, the rest were women and children.The number of women was 1 2/5 times the number of children.How many more more men than women were there?

For every 100 people, there were

40 men
30 women
30 children.

Use proportion to figure out the number for 2400 people.

my response is I didn't understand anything thank you

To find out how many more men than women were at the concert, we need to determine the number of men and women first.

Let's break down the information given step by step:

1. Total number of people at the concert = 2400
2. 40% of the total were men:
Number of men = 40% of 2400 = (40/100) * 2400 = 960

Now, to determine the number of women and children, we need to use the information that women were 1 2/5 times the number of children.

Let's find the number of children first:
Assume the number of children as x.
So, the number of women = 1 2/5 * x

To calculate the value of x, we can set up an equation using this information:

Number of women + Number of children = Total number of people - Number of men

(1 2/5 * x) + x = 2400 - 960

To simplify the equation, let's convert the mixed number 1 2/5 to an improper fraction:

(7/5 * x) + x = 1440

Multiplying through by 5 to eliminate the fraction:

7x + 5x = 1440 * 5

12x = 7200

Dividing both sides by 12:

x = 600

So, the number of children (x) is 600.

Now, we can determine the number of women:

Number of women = 1 2/5 * 600 = (7/5) * 600 = 840

To find out how many more men than women were there, subtract the number of women from the number of men:

Number of men - Number of women = 960 - 840 = 120

Therefore, there were 120 more men than women at the concert.
