Question

Describe how you labeled the bar model and wrote a number sentence to solve the problem involving 14 and 17. A) Labeled the bar model as "14" and "17," and wrote the number sentence as 14 + 17 = ____. B) Labeled the bar model as "14" and "17," and wrote the number sentence as 14 - 17 = ____. C) Labeled the bar model as "14" and "17," and wrote the number sentence as 14 x 17 = ____. D) Labeled the bar model as "14" and "17," and wrote the number sentence as 14 ÷ 17 = ____.

Answer 1

This question is about labelling bar models and writing number sentences to represent different mathematical relationships between the numbers 14 and 17. These relationships include addition, subtraction, multiplication, and division. Bar models are used in mathematics as a visual means to solve problems and understand concepts.

Step-by-step explanation:

The question is asking about different possible ways to use bar models to demonstrate mathematical relationships between two numbers, 14 and 17, in this case. A bar model is a graphical representation of a mathematical problem or concept. The numbers 14 and 17 in the question represent the lengths of the bars. Therefore:

• Option A: If you label the bar model as '14' and '17', and write the number sentence as 14 + 17 = ____, you are suggesting you are adding 14 and 17 together.
• Option B: Labeling the bar model with '14' and '17' and writing the number sentence as 14 - 17 = ____ suggests a subtraction operation where 17 is subtracted from 14.
• Option C: Labeling the bar model as '14' and '17', and writing the number sentence as 14 x 17 = ____ indicates a multiplication operation between 14 and 17.
• Option D: Labeling the bar model as '14' and '17', and writing the number sentence as 14 ÷ 17 = ____ suggests a division where 14 is divided by 17.
