\(\frac{20}{25}\)
We need to get the denominator to be 100. We can do that by multiplying the fraction by a form of 1.
\(\frac{20}{25} * \frac{4}{4} = \frac{80}{100}\)
From here, it should be easy to see that Matt has answered 80% of his test.
80% because 25 goes into 100 4 times and 20 times 4 equals 80.
