Solution
The correct option is D Fries < pizzas < burgers The total number of orders is 105. To compare 45,57, and 1535, we need to make their denominators 105.
Fraction of people who want to order burgers: 45=4×215×21=84105
Fraction of people who want to order pizzas: 57=5×157×15=75105
Fraction of people who want to order fries: 1535=15×335×3=45105 45105<75105<84105
Hence, the food items arranged in ascending order according to demand are: Fries < pizzas < burgers.
