Question

Choose the correct answer to the following exercise:

00:06 Let's solve this problem together.

00:09 First, put zero in the right spot. Then add the decimal point where it belongs.

00:14 Next, connect the points correctly, and then add the final touches.

00:24 Great job! And that's how we solve this question.

To avoid confusion, we will first add the digit 0 to the number 5.4 as follows:

$5.40\\+3.22\\$

Now let's solve the exercise in order:

We'll add the hundredths after the decimal point:

$0+2=2$

We'll then add the tenths after the decimal point:

$4+2=6$

Finally, we'll add the whole numbers before the decimal point:

$5+3=8$

Finally, simply solve the addition as follows:

$5.40\\+3.22\\8.62$

8.62
