Solve (1×10.3) + (10.1×4): Decimal Multiplication and Addition

Let's solve the exercise by first solving the two multiplication problems, and then combining them:

$1\times10.3=10.3$

Now let's break down 10.1 and multiply it by 4 as follows:

$(10+0.1)\times4=$

Let's multiply 4 by 10 and then by 0.1:

$40+0.4=40.4$

Now we have the exercise:

$10.3+40.4=$

We'll solve accordingly and get:

$50.7$
