Solve Decimal Subtraction: 2.2 - 1.5 Step-by-Step

$2.2-1.5=$

To solve the problem $2.2 - 1.5$, follow these steps:

• Step 1: Write down the numbers vertically, ensuring the decimal points are aligned:

$2.2$

$-1.5$

• Step 2: Begin subtraction from the tenths place (rightmost decimal place).

• Step 3: Subtract $5$ from $2$ in the tenths place, which necessitates borrowing:

  • Change $2.2$ to $2.1$ (borrowing 1 from the units place, making it $12$ tenths).

• Step 4: Perform the subtraction:

  • $12 - 5 = 7$ in the tenths place, with a carry back to units (effectively $1$ in the units becomes $0$).

  • $1 - 1 = 0$ in the units place.

Therefore, the result of $2.2 - 1.5$ is $0.7$.
