How do I solve a proportion

Question

n/4 = 5/6

Answer 1

Proportions are solved using cross multiplication.

 

n/4 = 5/6

 

When you cross multiply you multiply the numerator of the fraction on one side of the equality by the denominator of the fraction on the other side of the equality.

 

n*6 = 5*4

 

6n = 20 (isolate 'n' by dividing by 6 on both sides of the equality)

 

6n/6 = 20/6

 

n = 3.33 (repeating decimal) or you could represent it as n = 3 1/3

Answer 2

n/4=5/6

cross multiply

6*n=4*5

6n=20

n=20/6

n=3 2/6

n=3 1/3
