To find a simplified expression representing the total number of coins that Katherine, Claire, and Lisa have, we need to define a variable for the number of coins Lisa has.
Let's say Lisa has "x" coins. Since Lisa has twice as many coins as Katherine, Katherine would have x/2 coins.
Therefore, Claire would also have x/2 coins (since the problem doesn't provide any additional information about her number of coins).
To find the total number of coins that the three girls have, we can add the number of coins each girl has:
Total number of coins = Lisa's number of coins + Katherine's number of coins + Claire's number of coins
Total number of coins = x + x/2 + x/2
We can simplify this expression further by combining like terms:
Total number of coins = 2x/2 + x/2 + x/2
Total number of coins = (2x + x + x)/2
Total number of coins = 4x/2
Finally, simplifying it further gives:
Total number of coins = 2x
Therefore, a simplified expression representing the total number of coins that Katherine, Claire, and Lisa have is 2x.
