  5. Question 4 1 + 24 : 4 + 1 =

  6. Question 5 Peut-on construire un triangle IJL tel que : IJ = 12 cm IK = 3,5 cm et JK = 4,5 cm ?

  7. Correction

  8. Question 1 24 = 30 - 6

  9. Question 2 7 63 : 9 = 9  7 = 63

  10. Question 3 Calculer le triple de 1,3. 3,9 3 1,3 =

  11. Question 4 1 + 24 : 4 + 1 = 1 + 6 + 1 = 8

  12. Question 5 IJ = 12 cm JK+IK = 4,5 + 3,5 = 8 cm IJ > JK + IK donc on ne peut pas construire le triangle IJK.
