Question

There are 10 desks, 12 chairs and 4 cabinets. What's the ratio of chairs to all
items?

Answer 1

`\huge\boxed{6:13}`

Explanation:

By simply adding all of the items, you end up with 10 + 12 + 4, or 26 items. Then, simply set the number of chairs to the number of total items, or 12 : 26. This ratio can also be expressed as the fraction 12/26, and can be simplified into 6/13, or 6 : 13, by dividing both the numerator and denominator by 2.

Hope it helps :) and let me know if you want me to elaborate.
