Dominic answers 43 of the 50 questions on his spelling test correctly. Witch decimal represents the fraction of problems he answered incorrectly

First of all, lets first find out the decimal representing how many questions he got correct. So this would would 43/50 otherwise written as 0.86 or 86%. Now in a test score, 100% is the perfect rate so we can subtract 86% from 100% in order to get 14%. Since we are looking for a decimal representative for this problem, then we simply write 14% as 0.14. So to conclude, the decimal representative of the problems that were answered incorrectly is 0.14
