Use cross multiplication to solve the following proportion for x.

7/9 = x/27

( include steps)

x = 21

Step-by-step explanation:

It's easier, tho' not essential, to re-write this equation as

7        x

=

9       27

To cross-multiply:  draw an imaginary line diagonally through 9 and x.  Multiplying, we get 9x.  Do the same with the other diagonal, through 7 and 27:  we get 7(27) = 189.

Then we have a new equation without fractions:  9x = 189.

Solve for x.  To do this, divide both sides by 9, obtaining:

x = 21
