Question

Isaiah answered 43 of the 50 questions on his math test correctly. which decimal represents the fraction of problems he answered incorrectly

Answer 1

The ratio of questions answered correctly can be represented as,

`(43)/(50)`

So, the number of questions answered incorrectly can be represented as,

`1-(43)/(50)=(7)/(50)=0.14`

Therefore, the decimal which represents the fraction of problems Isaiah answered incorrectly is 0.14.
