Subtracting same signs decimals
When subtracting decimals with the same sign, you follow these steps:
1. line up the decimals.
2. Subtract the numbers as you would with whole numbers.
3. Keep the sign of the larger absolute value.
For example, let's subtract -2.3 from -7.1:
-7.1
- (-2.3)
---------
-4.8
So, -7.1 minus -2.3 equals -4.8.
To subtract decimals with the same sign, follow these steps:
Step 1: Line up the decimal points.
Step 2: Subtract the numbers as you would with whole numbers, ignoring the decimal points.
Step 3: Place the decimal point in the answer directly below the decimal points in the original numbers.
Step 4: Simplify, if needed, by moving the decimal point to its final position.
Example:
Subtract 2.3 from 4.7.
Step 1: Line up the decimal points:
4.7
- 2.3
Step 2: Subtract the whole numbers:
4
- 2
Step 3: Place the decimal point:
4 . 7
- 2 . 3
Step 4: Simplify:
2.4
So, 4.7 - 2.3 = 2.4
