Answer 2

Concept:

Step 1: Depending on how many digits after the decimal any given number can have, it is initially padded with zero.

For instance, when adding 3.456 to 7.1, the padding is done in accordance with 3.456 because that number has the same number of digits as the decimal point. We add two zeros after 1 because 3.456 has three digits after the decimal point. 7.1 to three decimal places is 7.100.

Step 2: The numbers are arranged vertically next to one another.

  7.100

+ 3.456

Step 3: Add the decimal numbers that are analogous to integers, then set the decimal point appropriately.

  7.100

+  3.456

---------------------

 10.556

Given:

13.57+29.49+23.46

Find:

13.57+29.49+23.46=?+50.79

Replace the question mark.

Solution:

13.57+29.49+23.46=66.52

66.52 - 50.79 = 15.73

Therefore the question mark can be replaced by 15.73
