Answer: Top right corner
Step-by-step explanation:
The mixed number 3 & 1/4 is the same as the improper fraction 13/4. It is a rational number since it's a fraction or ratio of two integers.
13/4 = 3.25 is not an integer. So that's why n is outside of the "integer" box, but inside the "rational" box.
In contrast,
is irrational because we cannot represent pi as a fraction of two integers. We can get an approximation like 22/7, but that won't be exact.
