Decimal Skill Enhancement

🧮 Understanding Decimals

Decimals are a fundamental part of mathematics and are used extensively in everyday life. To improve your skills with decimals, focus on understanding the basics and practicing regularly. Here's a comprehensive guide:

➕ Addition and Subtraction

When adding or subtracting decimals, align the decimal points vertically. Add zeros as placeholders if necessary.

  3.  45
+ 12.  60
----------
  16.  05

✖️ Multiplication

Multiply decimals as you would whole numbers. Count the total number of decimal places in the factors and place the decimal point in the product accordingly.

    2.5   (1 decimal place)
 x  1.5   (1 decimal place)
-------
   125
+ 25
-------
  3.75   (2 decimal places)

➗ Division

When dividing by a decimal, move the decimal point in the divisor to make it a whole number. Move the decimal point in the dividend the same number of places. Then, divide as usual.

Divide 7.75 by 2.5:

2.  5 | 7.  75  ->  25 | 77.5

    3.1
25|77.5
   -75
   ----
     25
   - 25
   ----
      0
