Question

$11:2+4\frac{1}{2}=$ ?

00:00 Solve

00:04 Let's write division as a fraction

00:10 Always solve multiplication and division before addition and subtraction

00:14 Let's break down 11 into 10 plus 1

00:21 Let's break down the fraction into a whole number and remainder

00:29 Let's calculate the whole fraction

00:41 Let's continue solving, add the half to the fraction

00:45 And this is the solution to the question

According to the order of operations, first place the division operation inside parenthesis:

$(11:2)+4\frac{1}{2}=$

Then solve the operations inside the parenthesis:

$11:2=\frac{11}{2}=5\frac{1}{2}$

Now we get the expression:

$5\frac{1}{2}+4\frac{1}{2}=10$
