Question

Solve for the variable in the following proportion.

n : 1/2 as 6 : 1

Answer 1

visualize fractions
n/(1/2) = 6/1
method one
when you divide by a fraction invert and multiply n/(1/2) = n(2/1)
now you have 2n = 6
divide by 2 to get n=3
method two
multiply across the =
n(1) =(1/2)(6)
n = 3
