James wants to send two gifts by mail. one package weighs 2 3/4 pounds. the other package weighs 1 3/4 pounds. what is the total weight of the packages?
The total weight of package is 4.5 pounds
Given that James wants to send two gifts
From given question,
Weight of one package = [tex]2\frac{3}{4} \text{ pounds }[/tex]
Convert the above mixed fraction to improper fraction
Multiply the whole number by the denominator.
Add the answer from Step 1 to the numerator.
Write answer from Step 2 over the denominator.
Therefore,
[tex]2\frac{3}{4} = \frac{2 \times 4 + 3}{4} = \frac{11}{4} \text{ pounds }[/tex]
Weight of other package = [tex]1\frac{3}{4} \text{ pounds }[/tex]
Similarly, converting to improper fraction, we get
[tex]1\frac{3}{4} = \frac{1 \times 4 + 3}{4} = \frac{7}{4} \text{ pounds }[/tex]
Total weight = weight of one package + weight of other package
[tex]\text{Total weight } = \frac{11}{4} + \frac{7}{4} = \frac{11+7}{4} = \frac{18}{4} = \frac{9}{2}\\\\\text{Total weight } = \frac{9}{2} = 4\frac{1}{2} \text{ or } 4.5[/tex]
Thus total weight of package is 4.5 pounds
