PERCENTAGES

REMEMBER - ALL YOU NEED IS 1%

                      AND TO FIND IT YOU DIVIDE BY 100

Example:-

          What is   23% of  370 km?
                        1% = 3.7km (370 ¸ 100)
                   ® 23% = 85.1 km (37 x 23)

Example:-

          Increase €230 by 15%.
                    1% = €2.30 (€230 ¸ 100)
               ® 15% = €34.50 (€23 x 15)
               ® Increased amount = €264.50 (€230 + €34.50)

Example:-

          Decrease €325 by 27%.
                    1% = €3.25 (€325 ¸ 100)
               ® 27% = €87.75 (€3.25 x 27)
               ® New amount = €237.25 (€325 - €87.75)

FRACTIONS

THESE ARE JUST AS STRAIGHT FORWARD.

WHATEVER FRACTION YOU ARE ASKED TO WORK OUT, WORK OUT ONE PORTION OF IT AND THEN FIND OUT THE AMOUNT THAT YOU NEED.

 

Example:-

          What is ⁵/₈ of €32?

          Step 1 - Find out what ¹/₈ is ® €4 (€32 ¸ 8)

          Step 2 - Find the amount that you need ® €20 (€4 x 5)

          So, ⁵/₈ of €32 = €20

 

Example:-

          Find ⁷/₁₂ of €60.

          Step 1 - Find ¹/₁₂ ® €5 (€60 ¸ 12)

          Step 2 - Find your amount ® €35 (€5 x 7)

          So, ⁷/₁₂ of €60 = €35

 

                                                AND THAT’S IT!
