So you will first need to divide 123 by 2.4 to get how many male birds are there. Then you need to multiply that answer by 0.4. That will be your final answer.
An=a1+(n-1)×d
1+(n-1)×5
1+5n-5
An= 5n-4
Answer:

difference between 3/4 and 1/3 is
5/12 i believe
Step-by-step explanation:
just change to common denominator and find the difference
To simplify this fraction, multiply the entire fraction by the conjugate of the denominator. The conjugate of a square root and a number being added to it would be the number <em>subtracted </em>from the square root. In other words, the conjugate of 
would be
.
Applying that information to our fraction shown here, the conjugate of the denominator would be 
. We will multiply both the numerator and denominator of our original fraction by this expression to obtain our answer, as shown below.
Our answer is 
.
