Solution:
Given that,
Craig and Alissa are building a sandcastle on the beach. They each have a bucket
Craig's bucket holds 1/2 pound of sand and Alissa's bucket holds 9/10 pound of sand
Therefore,
[tex]Craig\ bucket = \frac{1}{2}\ pound\\\\Alissa\ bucket = \frac{9}{10}\ pound[/tex]
How much sand can craig Alissa collect together at one time
Add both, we get
[tex]Collect\ together = \frac{1}{2} + \frac{9}{10}\\\\Collect\ together = \frac{1 \times 5}{2 \times 5} + \frac{9}{10}\\\\Collect\ together = \frac{5}{10} + \frac{9}{10}\\\\Collect\ together = \frac{9+5}{10}\\\\Collect\ together = \frac{14}{10} = \frac{7}{5} = 1.4\\\\In\ mixed\ fractions,\\\\Collect\ together = 1\frac{2}{5}[/tex]
Thus, amount of sand craig and Alissa collect together at one time is 1.4 pounds
