What is the value of 0.6 - (0.7)(1.4)?

Rationale

-0.38

To solve the expression 0.6 - (0.7)(1.4), we first calculate the product of 0.7 and 1.4, which equals 0.98. Subtracting this value from 0.6 gives us -0.38, confirming it as the correct answer.

A (-0.38) CORRECT

This choice is the correct answer. As calculated, 0.6 - 0.98 results in -0.38, accurately reflecting the mathematical operation.

B (-0.14) YOUR ANSWER

This option arises from a common miscalculation. If one incorrectly adds rather than subtracts, they might end up with 0.6 - 0.7 + 1.4, which does not correspond to the original expression. Thus, this choice is incorrect.

C (-0.42) YOUR ANSWER

Choosing -0.42 might stem from a misinterpretation of the multiplication or subtraction steps in the expression. When properly calculated, the product 0.98 should be subtracted from 0.6, leading instead to -0.38, not -0.42.

D (-1.5) YOUR ANSWER

This answer is significantly off from the correct calculation. The confusion may arise from an incorrect application of the order of operations or from miscalculating the product of 0.7 and 1.4. The correct calculation yields -0.38, making -1.5 an invalid choice.

Conclusion

The value of the expression 0.6 - (0.7)(1.4) simplifies to -0.38 after careful calculation. The other options represent common errors in arithmetic or misunderstanding of operational order. Understanding how to properly evaluate expressions is crucial for accurate mathematical reasoning.
