Question 534096
Since you got 68% (or 0.68 as the decimal equivalent) correct, you can multiply that factor proportion times 25 to find the number you got right:
.
{{{0.68*25 = 17}}}
.
So you got 17 correct. That means that you missed 8 out of the 25 questions.
.
Therefore, the ratio of correct answers to incorrect answers is 17:8 or in fractional form is:
.
{{{17/8}}}
.
And by dividing 17 by 8 you get a ratio of 2.125:1 or 2.125 to 1.
.
Depends on how you're being taught or what your teacher wants to see. The answer can be written as {{{17/8}}} or 17:8 or 17 to 8 or 2.125:1 or 2.125 to 1, they all are equivalent.
.
Hope this helps you to understand how to do this problem.
