Answer: The answer is 0.14.
Step-by-step explanation: Given that there are 50 questions in the spelling test which Dominic has to answer. Also, it is given that Domonic answered 43 questions correctly.
Therefore, the number of questions that he answered incorrectly
= 50 - 43
=7.
So, the fraction of problems that Dominic answered incorrectly is given by
![n=(7)/(50)=0.14.](https://img.qammunity.org/2020/formulas/mathematics/high-school/n2dti6t804t9wa03pioyh9jcijeq9c9bbt.png)
