Enter proportion values below:

  
---------- ----------
  
  
Numerator 1  =  Denominator 1 * Numerator 2
  Denominator 2

3t  =  20 * 45
  1

3t  =  900
  1

Answer
Success!
t = 300

↓Steps Explained:↓

You entered the following equivalent proportions:

3t
20
=
  
45
1

Define the proportion formula:

If 2 proportions are equal:
we can cross multiply to get:

Numerator 1
Denominator 1
=
  
Numerator 2
Denominator 2

Numerator 1 * Denominator 2 = Denominator 1 * Numerator 2

Solving for Numerator 1 we get:

Numerator 1  =  Denominator 1 * Numerator 2
  Denominator 2

Evaluate and simplfy

3t  =  20 * 45
  1

3t  =  900
  1

3t  =  900

Divide each side by 3

3t
3
=
