A = 24 When B Is , What Is A If B = 3?

A = 24 when b is , what is a if b = 3?

 

Answer:

b= 1/4

Step-by-step explanation:

This is an example of inverse proportion, or inverse variation.

To change a proportion into an equation, multiply by a constant and then use the values given to find the value of the constant.

aprop 1/b rArr a = k/b rArr k = a

Find the value of k, using the a and b given.

k= 3xx4 = 12

So, a = (12)/b " can also be written as " b = 12/a

When a = 48, " " b = (12)/(48) = 1/4
