To find the sum of the numbers 5.81, 67.9, and 94.35, we can align the numbers by their decimal points and add them together:
5.81
+67.90
+94.35
-------
Now, let's add them column by column starting from the rightmost column (hundredths place):
- Hundredths place: \(1 + 0 + 5 = 6\)
- Tenths place: \(8 + 9 + 3 = 20\) (write down 0, carry over 2)
- Units place: \(5 + 7 + 4 + 2 (carry) = 18\) (write down 8, carry over 1)
- Tens place: \(6 + 9 + 1 (carry) = 16\) (write down 6, carry over 1)
- Hundreds place: \(1 (carry) = 1\)
Putting it all together, we get:
5.81
+67.90
+94.35
-------
168.06
Therefore, the sum of 5.81 + 67.9 + 94.35 is 168.06.
