Question

Ratio of boots so the sandals was 9:4 if there were 36 sandals sold how many boots were sold

Answer 1

81 boots

Explanation:

We know that the ratio of boots to sandals was 9:4, and we know that 36 sandals were sold. Using this, we can make a proportion, with "b" being the number of boots.

9/4 = b/36

Then, we need to turn the denominator of 9/4 (which is 4) into 36.

36/4 = 9

So now, we do 9/4*(9/9), which will give us 81/36

Plug into the proportion

81/36 = b/36

We can get rid of the denominators since they are the same.

b = 81

Hope this helps!
