In two compounds masses of B are 20 grams and 50 grams while A is fixed. What is the simple ratio?

Answer and explanation

Correct answer: 2:5

Since the mass of A is fixed, compare the masses of B in the given order: 20:50. Dividing both terms by 10 gives the simplest ratio, 2:5. The ratio 5:2 is the reverse order, so it is not correct here. Exam tip: write ratios in the same order as the quantities stated in the question.
