A city has 5 houses for every 8 old houses. If there are 35 new houses in the city, how many old houses are there?
1 answer:
Answer:
56 old houses
Step-by-step explanation:
For every 8 old houses there are 5, so there are 3 more.
For this reason, if there are 35 houses, it means that there are 5 times the houses.
So if we multiply 3 by 5 (which is the difference between old and new houses) it would give 21, which when adding it to 35 gives 56
