This site will help students see how mathematics can play a part in all aspects of life. Students will see different careers and occupations that they could have and how mathematics plays a part in it. Students may select a career and will be give a lesson that will fit in that field.

Cooking for a large group is easy for chefs. They can change a recipe that serves 4 to service for 20. This is done by increasing or decreasing the ingredients. Sometimes they may need to multiply or divide fractions, mixed or whole numbers.

Examples: The recipe for four people
calls for
3½ cups flour. To increase the service to 20 you multiply by 5.

3½ × 5 =

7/2 ×5 = 17½ cups

¼ cup oil increase by 5

¼ × 5 =

¼ × 5 = 1¼ cups

Dentistry calls for precise measurements. A dentist
must
understand the metric system. He/She needs to be able to change
measurements from
one unit to another.

Examples: 4cm =40mm

80mm=8cm

2.5cm=25mm

Entertainers need to be aware of their finances. Having a budget is important and so is understanding percentages.

Example: A singer making $10,000 per performance must pay 28% in taxes
and 15% to her agent.

10000 × 0.28 = 2800

10000 × 0.15 = 1500

In baseball a batter hits a line drive at 100 ft./sec. How long would an out fielder have to get into position if he's 200 ft. away?

Example: d = r × t

200 =100 × t

2 = t
