A science class has a total of 33 students. The number of females is 15 less than the number of males. How many males and how many
females are in the class?



Number of males:
Number of females:



Answer :

Let's say the number of males is x. Since the number of females is 15 less, the number of females is x - 15. We know that the total number of students is 33, so x + (x - 15) = 33. Simplifying the equation, we get x = 20 and x - 15 = 5. So, there are 20 males and 5 females in the class.

Answer:

Let's denote the number of males as \(M\) and the number of females as \(F\).

We know that the total number of students is 33:

\[ M + F = 33 \]

The problem also states that the number of females is 15 less than the number of males:

\[ F = M - 15 \]

Now, you can solve these two equations simultaneously to find the values of \(M\) and \(F\).

Substitute the expression for \(F\) from the second equation into the first equation:

\[ M + (M - 15) = 33 \]

Combine like terms:

\[ 2M - 15 = 33 \]

Add 15 to both sides:

\[ 2M = 48 \]

Divide by 2:

\[ M = 24 \]

Now that you know the number of males (\(M\)), substitute this value back into the second equation to find \(F\):

\[ F = 24 - 15 = 9 \]

So, there are 24 males and 9 females in the class.
