Sometimes the comparison has a missing number. 4 times what equals 36? We can use a letter: 4 × n = 36.
Think: what number, copied 4 times, makes 36? 36 divided by 4 is 9, so n is 9.
Or the times can be missing. Nia has 3 stamps and Kai has 24. How many times as many does Kai have? 8 times 3 is 24, so 8 times as many.
