Simplifying (rac{5}{13} + rac{3}{4}) + rac{1}{4}
Simplify the expression (rac{5}{13} + rac{3}{4}) + rac{1}{4} by using the associative property of addition to group the fractions with common denominators together.
Notice that the last two terms share the common denominator . Change the grouping by shifting the parentheses to associate them:
rac{5}{13} + (rac{3}{4} + rac{1}{4})
First, add the fractions within the parentheses by combining their numerators over the common denominator:
rac{5}{13} + (rac{4}{4})
Simplify the fraction rac{4}{4} to :
rac{5}{13} + 1
Add to get a mixed number:
1 rac{5}{13}
Finally, convert the mixed number to an improper fraction:
rac{18}{13}
0

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.

As an operations supervisor, you are reviewing a time-tracking report for a three-part assembly process. The time taken for each part (in hours) is logged as the expression . To calculate the total time efficiently without needing to find a complex common denominator first, you recall that you can use the associative property of addition to regroup the fractions. Which of the following shows the correct first step applying this property?
True or False: To simplify the expression efficiently using the associative property of addition, you should regroup the terms to first add the fractions with common denominators, resulting in the equivalent expression .
A warehouse supervisor is totaling the weights of three metal components for a cargo manifest. The weights in tons are represented by the expression . To simplify the calculation efficiently, the supervisor uses the associative property of addition to group the common denominators. Arrange the following steps in the correct order to simplify the expression.
A logistics coordinator is totaling the weights of three cargo shipments recorded as {}(rac{5}{13} + rac{3}{4}) + rac{1}{4} tons. To calculate the total efficiently, the coordinator follows a specific sequence of steps to group and simplify the fractions. Match each step description with the corresponding mathematical expression produced in that stage.
An inventory auditor is calculating the total volume of chemical solvents across three containers. The volumes (in gallons) are logged in the system and initially grouped as . To make the calculation much simpler without finding a complex common denominator first, the auditor regroups the expression to so they can easily combine the fractions with the same denominator. The mathematical rule that allows for this shifting of parentheses without changing the final total is called the ____ property of addition.
