# Crate and Barrel shipped three packages to New York weighing 45 1 5 , 126 3 4 , and 88 3 8 pounds. What was the total weight of the shipment?

To determine

To calculate: The total weight of the shipment of three packages weighing 4515,12634 and 8838 pounds which were shipped to New York by Crate and Barrel.

Explanation

Given information:

The weight of the three packages that were shipped to New York by Crate and Barrel are 4515,12634 and 8838.

Formula used:

Use the following steps for adding the unlike fractions.

Step1: First add the fractional parts and also convert it to mixed fraction if the sum is in the improper fraction.

Step2: Now add the whole number.

Step3: Add the fraction from step1 to the whole number from step 2.

Step4: Reduce the answer to the lowest terms if necessary.

Now use the following steps for determining the least common denominator of two or more fractions with the use of prime number are,

Step1: Write all the denominators in a row.

Step2: Now find a prime number that divides evenly into any of the denominators and then write that prime number to the left of the row and divide while placing all quotients and undivided numbers in the next row down.

Step3: Repeat the above process until new row contains all ones.

Step4: Multiply all the prime numbers on the left to get the LCD of the fractions.

Calculation:

Consider the data about the weight of the three packages that were shipped to New York by Crate and Barrel as 4515,12634 and 8838.

The total weight of the shipment is equal to sum of weight of three packages.

4515+12634+8838

As these are unlike fractions and they must be converted to obtain the same denominator so find the LCD.

25,4,825,2,425,1,255,1,1

And,

1,1,1

The Least Common Denominator (LCD) is 2×2×2×5=40
