Q14:

Let's say you have 70 tables and you want to make a square formation.

It's clearly impossible to have 8.3666... tables, so we round down to 8.

Even though you didn't use all 70 tables, you still made a square with the most numbers of table possible.

I don't have an answer to the question...but:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
