Solve Decimal Addition: 0.7 + 0.4 Using Visual Blocks

Question

$0.7+0.4=$

00:00 Solve

00:03 We will use long addition for calculation

00:08 We will place the decimal point in the appropriate position

00:12 We will start by adding the smallest appropriate digits

00:21 We will place the units and remember 1 above

00:29 We will add 1 to this calculation

00:34 And this is the solution to the question

To solve this problem, we will add the two decimal fractions $0.7$ and $0.4$ .

Let's break down the process:

Step 1: Align the numbers by their decimal points:
$\phantom{+}0.7$
$+0.4$
Step 2: Add the numbers column by column starting from the rightmost place (tenths place):
$7 + 4 = 11$
Step 3: Write down the 1 in the tenths place and carry over 1 to the units place. There is no whole number component in this addition, so simply add the carry to $0$ which is $1 + 0 = 1$ .
Step 4: Combine the results to find the total: $1.1$ .

Thus, the sum of $0.7$ and $0.4$ is $\mathbf{1.1}$ .

The correct choice is 1: 1.1.
