A city has 4 new houses for every 7 old houses. If there are 32 new houses in the city, how many old houses are there?

So the ration is 4:7

The total of houses is 32 new houses. What I did was I divided 32 by 4:

32/4 = 8

That means that the ratio (4:7) would be multiplied by 8 (only the :7 part):

7 * 8 = 56

There are 56 old houses (the ratio is now 32:56)

Thank you and can you please give me :3
