Answer 1

Paulo made his first mistake when he multiplied 0.25 by 0.25. In the equation, he correctly multiplied 16 by 0.25 to get 4. However, when he multiplied 0.25 by 0.25, he made an error. The correct multiplication of 0.25 by 0.25 is 0.0625, not 0.25. This mistake led to an incorrect result in the equation.
To solve the equation correctly, Paulo should have multiplied 0.25 by 0.25, which would give him 0.0625. Then, he could proceed with the calculation by subtracting 0.0625 from 16, resulting in 15.9375. Therefore, the correct answer is A - 0.25.
