In this article, the authors present an inquiry activity presented to Year 7 students in a mathematics excellence class at a P-12 school in regional Queensland. Different students solved the activity (comparing the sugar content of fruit) using decimals, percentages, ratio and rates. By asking the students to solve a problem they were much more engaged with their learning than they would have been if they had been given a table from the textbook and asked to complete the conversions. Some questions to support the inquiry are included.
