6. 2 x 10 12 2 2.4 10 12 •12 1 •12 1 24 x 10 2 – Use algebra to solve Do the opposite operation to solve for the variable. For example: 2.4 = x Do on your own: 7/6 = x/10

7. 4 10 9 ? 4 10 9 22.5 2 5 11 ? 3 – cross multiply Multiply the numbers diagonally to find out what’s missing For example: 9 x 10 = 90 4 x _____ = 90 Do on your own: 22.5

8. p.389 #3-7 • 5/6 = ___/18 • 15/20 = ___/4 • ___/6 = 4/2 • ___/5 = 5/25 • 35/12 = ___/2
