Simplifying (rac{7}{15} + rac{5}{8}) + rac{3}{8}
Simplify the expression (rac{7}{15} + rac{5}{8}) + rac{3}{8} by applying the associative property of addition to group the fractions with common denominators.
Since the second and third fractions share a denominator of , change the grouping to add them together first:
rac{7}{15} + (rac{5}{8} + rac{3}{8})
Add the fractions inside the parentheses:
rac{7}{15} + (rac{8}{8})
Simplify the fraction inside the parentheses to :
rac{7}{15} + 1
Add to form a mixed number:
1 rac{7}{15}
Convert the fraction to an improper fraction:
rac{22}{15}

A project manager is totaling expenses for a marketing campaign: Advertising ($2,500), Printing ($500), and Travel ($1,200). They calculate the sum as ($2,500 + $500) + $1,200, but then realize it is easier to calculate $2,500 + ($500 + $1,200). Which mathematical property ensures that both methods result in the same total?
In a corporate accounting department, a clerk is summing three separate invoices. The clerk notices that grouping the first two invoices together before adding the third yields the same total as adding the first invoice to the sum of the last two. This mathematical principle is called the ____ property of addition.
In a retail setting, the associative property of addition states that when totaling the sales of three different registers, the way the register totals are grouped (for example, using parentheses to group the first two totals) does not change the final sum.
Match each aspect of the Associative Property of Addition with its correct representation as it would be used in a workplace inventory audit.
