Solution

## The correct options are B 12×(6−3)=(12×6)−(12×3) C (8+10)×15>8+(10×15) (A) 5×(8+10)=5×8+5×10 (using distributivity of multiplication over addition) So, 5×(8+10)≠10×(8+5) (B) 12×(6−3)=(12×6)−(12×3) This is the correct law of distributivity of multiplication over subtraction. (C) (8+10)×15>8+(10×15) Here, (8+10)×15=18×15=270 8+(10×15)=8+150=158 So, this is correct. (D) (−11)×(−3)×(2) =11×3×2=66 So, (−11)×(−3)×(2)≠−66 [When we multiply 2 negative numbers, we get a positive number. So, answer should be 66 instead of (−66)]  Suggest Corrections  1      Similar questions  Explore more
