An inventory clerk at a logistics center is calculating the total weight of three packages using the expression (rac{2}{9} + rac{7}{12}) + rac{5}{12} tons. To simplify the mental calculation, the clerk regroups the terms as rac{2}{9} + (rac{7}{12} + rac{5}{12}). Which mathematical property justifies this regrouping?

A payroll specialist is tallying fractional hours spent on three different project phases, initially calculated as $\left(\frac{2}{9} + \frac{7}{12}\right) + \frac{5}{12}$. True or False: By changing the grouping to combine the fractions with identical denominators first, the specialist simplifies the problem to the intermediate step $\frac{2}{9} + 1$.

A logistics coordinator at a shipping center needs to find the total weight of three packages. The weights are given by the expression (rac{2}{9} + rac{7}{12}) + rac{5}{12} kilograms. Arrange the following steps in the correct order to simplify this expression by regrouping the terms with identical denominators.

A project supervisor is calculating the total weight of three components measured in tons using the expression (rac{2}{9} + rac{7}{12}) + rac{5}{12}. To simplify the mental math, the supervisor regroups the terms to add $rac{7}{12}$ and $rac{5}{12}$ first. This specific sum, $rac{12}{12}$, simplifies to the whole number ____.

A logistics coordinator is calculating the total weight of three cargo crates in tons using the expression (rac{2}{9} + rac{7}{12}) + rac{5}{12}. Match each part of the simplification process with its corresponding mathematical role or resulting value.
