Describe a real world situation that could be modeled by dividing 2 rational numbers?

A possible answer is:

"I have 0.5 of a pizza left. There are 3 people eating it for lunch. What part of the whole pizza is each person eating for lunch?"

Explanation:

Rational numbers are any numbers that can be written as fractions. Whole numbers can be written as fractions, too, by writing them over a denominator of 1. This means we want to create a problem involving division of fractions and/or whole numbers.

only 10/60 isn't equivalent

hope this : )
