Question

Lee and Fred are elementary school teachers. Fred works for a charter school in Pacific Palisades, California, where class size reduction is a goal for 2013. Lee works for a noncharter school where funds do not allow for class size reduction policies. Lee’s fifth-grade class has 1.4 times as many students as Fred’s. If there are a total of 60 students, how many students does Fred’s class have? How many students does Lee’s class have?

Answer 1

Answer:

25,35

Step-by-step explanation:

We'll call fred's class size x. We know that lee's clas is 1.4 times bigger than fred's so it is 1.4x. Now, their total is 60, so 60/2.4 = x  x=25

so Fred's class has 25 so Lee's class has 35.

Answer 2

Answer:

Fred’s class has 25 students.

Lee’s class has 35 students.

Step-by-step explanation:

You know that Lee’s fifth-grade class has 1.4 times as many students as Fred’s, then you can write the following expression:

$L=1.4F$

Where L is the number of students that Lee’s class has and F  is the number of students that Fred’s class has.

You know that there are a total of 60 students, then you can write the following expression:

$L+F=60$

Substitute $L=1.4F$ into the second equation and solve for F:

$1.4F+F=60$

 $2.4F=60$

 $F=60/2.4$

 $F=25$

Then, L is:

$L=1.4*25=35$
