Question

Why is the Associative property useful for Rational numbers?

• A. For conversions
• B. For ease of calculations
• C. For ease of interpretation
• D. Not useful

Answer 1

Answer: (B), (C)

The correct options are
B

For ease of calculations

C

For ease of interpretation

The Associative property makes the calculation or interpretation Easier at times.

Example : 7 $\times$ 25 $\times$ 40

If we calculate 7 $\times$ 25 = 175 and then multiply it with 40, the calculation is a bit long and consumes more time.

If we simply do 25 $\times$ 40 we get 1000 and then multiplying it with 7 we get 7000 which is a simpler calculation.
