In this question, we’re given two ratios that are equal or equivalent, six to 36 and something to six. We can scale ratios up or down by multiplying and dividing. Whatever we do to the right-hand side, we must do to the left-hand side. In this case, how can we get from 36 to six?

36 divided by six is equal to six. As we have divided the right-hand side by six, we need to divide the left-hand side by six. Six divided by six is equal to one. The ratio six to 36 is equal to the ratio one to six. This means that the missing number is one.
