Answer 3

Cross-multiplication works great.

Answer 4

e.g. given a/b = c/d --> ad = bc. Then go from there.

Answer 5

Here's an example.

Solve the proportion:

\( \dfrac{12}{19} = \dfrac{x}{76} \)

Cross multiply:

\(19x = 12(76)\)

\(19x = 912\)

Now divide both sides by 19:

\(\dfrac{19x}{19} = \dfrac{912}{19} \)

\(x = 48\)

Answer 6

Here's a short cut:
Start with the number on the same fraction as the variable. Multiply diagonally. Divide vertically. It always works no matter where the variable is.
