The ratio of male to female at a cinema was 7:9. How many male were there if there were 630 female
Let's assume that the ratio of males to females at the cinema is 7x:9x (where x is a common factor).
We are told that there were 630 females, so the ratio 9x represents 630.
To solve for x, we set up the following equation: 9x = 630.
Simplifying the equation, we find that x = 630/9 = <<630/9=70>>70.
Since the ratio of males to females is 7x:9x, the ratio of males to females is 7(70):9(70) = 490:630.
Therefore, there were 490 males at the cinema.
To find the number of males, we first need to determine the total number of people at the cinema.
Let's assume that the number of males is represented by 7x, where x is a common multiple.
Given that the ratio of male to female at the cinema is 7:9, we know the number of females is represented by 9x.
We are also given that there were 630 females, so we can set up the equation:
9x = 630
To solve for x, divide both sides of the equation by 9:
9x/9 = 630/9
Simplifying, we get:
x = 70
Now that we have the value of x, we can substitute it back into the equation for the number of males:
7x = 7 * 70 = <<7*70=490>>490
Therefore, there were 490 males at the cinema.
