Example #1 – Additions Combinations of Decimal and Whole Numbers
7.7 + 7.77 + 7.777 + 7.7777 + 7.77777 + 7.777777 = ?
The result of the addition is 7.7 + 7.77 + 7.777 + 7.7777 + 7.77777 + 7.777777 = 46.580247.

Shortcut Tricks

  1. Take 7 Common and Replace all 7 with 1,
    7(0.1 + 0.11 + 0.111 + 0.1111 + 0.11111 + 0.111111)
  2. Count number of digits after the decimal place.
    i.e, 0.1=1(digit), 0.11=2(digit), 0.111=3(digit), 0.1111=4(digit), 0.11111=5(digit), 0.111111=6(digit).
  3. Write down all digits together but in reverse order like, 0.654321
  4. Multiply 7×0.654321 = 4.580247
  5. Now Multiply the Whole number with the total numbers present in the group.
    i.e, 7 x 6 = 42

    Example 3:
    7.7+7.77+7.777+7.7777+7.77777+7.777777
    The result of the addition is 7.7+7.77+7.777+7.7777+7.77777+7.777777 = 54.3580247.

    Shortcut Tricks
    Step 1: At First we can calculate the Decimal number 7 ( 0.7654321 ) = 5.3580247
    Step 2: In Step 2 we can calculate the Whole numbers that is maximum number 7 digits is
    = 7+7+7+7+7+7+7 So, 7 x 7 = 49
    Step 3: Now we can add both result of step 1 and Step 2 = ( 49 + 5.3580247 ) = 54.3580247.

    In the above sum question is in wrong format add 7.7777777 to above quation
