Word problems on adding decimals:

2. Terry spent $33 and 65 cents on Monday, $21 on Tuesday and $9 and 7 cents on Wednesday. Find the total money spent by her in three days altogether.

Solution:

Terry spent on Monday = $43 and 65 cents                                = $33.65

She spent on Tuesday = $21                                                   = $21.00

She spent on Wednesday = $9 and 5 cents                                =  $9.07

Therefore, total amount spent by Terry = $(33.65 + 21.00 + 9.07) = $63.72


3. First number is 85.99, second number is 107.81 and the third number is 19.207. Find the sum of the three numbers.

Solution:

First number = 85.99

Second number = 107.81

Third number = 19.207

Therefore, sum of three numbers = (85.99 + 107.81 + 19.207) = 213.007
