1. 1. FRACTIONS – WORD PROBLEMS
2. 2. The 3 Little Pigs…. Goes to Pizza Hut
3. 3. Once upon a time, there lived 3 lovely, little pigs. They were called Pig 1, Pig 2 and Pig 3.
4. 4. The 3 pigs were famished so they decided to head down to the nearest Pizza Hut.
5. 5. Within 10 minutes of placing their order, the piping hot pizza was finally served to them .
6. 6. Being the eldest, Pig 1 was allowed to eat of the pizza. How many slices of pizza did he eat?
7. 7. Being the eldest, Pig 1 was allowed to eat of the pizza. How many slices of pizza did he eat? Using concept of ‘fractions of a set’ 1 Of 6 = 1 x 6 3 3 1 = 1 x 6 3 x 1 = 6 3 = 2 Pig 1 ate 2 slices of pizza
8. 8. Pig 2 then ate of the pizza. What is the fraction of the pizza eaten by Pig 1 and Pig 2?
9. 9. Pig 2 then ate of the pizza. What is the fraction of the pizza eaten by Pig 1 and Pig 2? Using concept of ‘addition of fractions’ 1 + 1 = 2 + 1 3 6 6 6 = 3 6 = 1 2 The fraction of pizza eaten by Pig 1 and Pig 2 is
10. 10. What is the fraction of pizza left for Pig 3 to eat?
