Baker A baker has to know how much ingredients to put in food. He uses decimals to measure. He also has to know fractions because he bakes pies. A baker has to know how much ingredients to put in food. He uses decimals to measure. He also has to know fractions because he bakes pies. Example: A baker needs 100 oz of milk. He can only measure in cups. So he knows that 8oz=1 cup and 100 oz = 100/8 = 12.5 cups. So he needs 12.5 cups of milk. Example: A baker needs 100 oz of milk. He can only measure in cups. So he knows that 8oz=1 cup and 100 oz = 100/8 = 12.5 cups. So he needs 12.5 cups of milk. 8 oz (US) = 1 cup 100 oz = 100/8 = 12.5 cups 8 oz (US) = 1 cup 100 oz = 100/8 = 12.5 cups 12.5 cups are 100 oz cups are 100 oz.

Builder A builder uses rational numbers by having to know the perimeter of a room using decimals. A builder uses rational numbers by having to know the perimeter of a room using decimals. Example: If a room is rectangle with a length of 48 cm and width of 12 cm, the Builder has to times 48x2 and 12x2 and then add them together to get the perimeter. Example: If a room is rectangle with a length of 48 cm and width of 12 cm, the Builder has to times 48x2 and 12x2 and then add them together to get the perimeter. 48x2=96 12x2= =120 48x2=96 12x2= =120

Time for a commercial break……
