Multiplying fractions

• To multiply fractions, first we simplify the
  fractions if they are not in lowest terms. Then
  we multiply the numerators of the fractions to
  get the new numerator, and multiply the
  denominators of the fractions to get the new
  denominator. Simplify the resulting fraction if
  possible.
• Example 2/7 5/2 10/14 then simplify (5/7)
• Then do the same to other fractions to multiply
  them.

Dividing fractions

• To divide fractions you invert (flip) the second
  fraction and multiply the fractions.
• Multiply the numerators and denominators of the
  fractions.
• Then simplify the fraction.
• 2/15 divided by 4/30
• Then flip 4/30 to make 30/4
• Then multiply the fractions 60/ 450 and simplify
  to lowest terms...
