Question 20

21.8 x 0.35 equals 7.63

Multiplying 21.8 by 0.35 results in 7.63, demonstrating the correct application of decimal multiplication.

A) 0.5705

Option A is incorrect because 0.5705 does not reflect the product of 21.8 and 0.35. This result is significantly lower than what would be expected from the multiplication of these two numbers.

B) 0.763

Option B is also incorrect. While 0.763 is a number close to the decimal range, it does not accurately represent the product of 21.8 and 0.35, which should yield a larger value.

C) 76.3

Option C is not correct because 76.3 is too high for the result of multiplying 21.8 by 0.35. This figure suggests an erroneous interpretation of the decimal placement in the multiplication.

D) 5.705

Option D is incorrect as well, since 5.705 is lower than the expected result of 7.63. This value does not accurately reflect the multiplication of the two given numbers.

E) 7.63

Option E is the correct answer because it accurately represents the product of 21.8 and 0.35, which is calculated as 7.63.

Conclusion

The correct answer is definitively 7.63, as it is the accurate product of the multiplication of 21.8 and 0.35. All other options fail to represent the correct calculation, either being too low or too high, indicating a misunderstanding of decimal multiplication principles.
