Question 1

A display has 18 red notebooks and 30 blue notebooks. What is the ratio of red notebooks to blue notebooks in simplest form?

  1. Red to blue is 3:5 after simplification.Bonne réponse
  2. Red to blue is 5:3 after simplification.
  3. Red to blue remains 18:30.
  4. Red to all notebooks is 3:8.

Explication

The stated order puts the 18 red notebooks before the 30 blue notebooks, and dividing both terms by 6 gives 3:5. Reversing the terms to 5:3 would describe blue notebooks compared with red notebooks instead.
