A building has two sizes of apartments, small and regular. The ratio of small apartments to regular apartments is 14 to 6. What percent of apartments in the building are small?

Step-by-step explanation:

Given

Represent Small Apartments with S and the Regular ones with R

Required

Determine the percentage of small buildings

This is calculated as thus:

Substitute values for S and R

Hence, the percentage if the small apartments is 70%

Note that if we're to calculate the percentage of the regular ones, the formula would have been:

Just copying this over just in case others with similar questions turn this up in search results rather than the other, haha!
When you multiply or divide a negative by another negative, you get a positive. When it is a negative and a positive, it remains negative.
Assuming your question simplified into a equation (or number form? Been a while, haha!) is 32÷-2÷(-16÷4), it would end as a positive. Because you first divide the positive 32 by a negative 2, you get a negative. Because -16÷4 is in parenthesis, it is done because following the rest of the equation (P.E.M.D.A.S.!), it would be 32÷-2÷-4. Going from left to right, as you should, it results in a negative being divided by another negative, so you get a positive. 32÷-2÷(-16÷4) = 32÷-2÷-4 = -16÷-4 = 2!
