Examples of Number Sentence

  • If there are 5 candies and the cost of each candy is 12 cents, then the cost of 5 candies in the form of a number sentence is written as:
    5 � 12 = 60, i.e. the cost of 5 candies = 60 cents.
  • The cost of 1 apple is $2 and the cost of 7 apples is $14. So, the number sentence that represents the situation is 7 � 2 = 14.

Solved Example on Number Sentence

Ques: Which of the given number sentences is true?

    Choices:
    A. 40 + 20 <>
    B. 8 � 4 = 22
    C. 40 - 20 = 18
    D. 40 � 8 = 15
    Correct Answer: A

Solution:

    Step 1: An inequality also represents a number sentence. So,
    40 + 20 < 80="">
    60 < 80="" is="">
    Step 2: 8 � 4 = 32 but the number sentence given 8 � 4 = 22 is not true.
    Step 3: 40 - 20 = 20 but not 18 and hence the number sentence 40 - 20 = 18 is not true.
    Step 4: 40 � 8 = 5 but not 15 and hence the number sentence 40 � 8 = 15 is also not true.
    Step 5: Hence the number sentence 40 + 20 < 80="" is="">
