Calculate 1/2 + 3½ + 4¾: Mixed Number Addition Problem

According to the order of operations, we must solve the exercise from left to right.

Let's note that in the first addition exercise, we have an addition between two halves that will give us a whole number, therefore:

$\frac{1}{2}+3\frac{1}{2}=4$

Now we will get the following exercise:

$4+4\frac{2}{4}=$

Let's note that we can simplify the mixed fraction:

$\frac{2}{4}=\frac{1}{2}$

Now the exercise we get is:

$4+4\frac{1}{2}=8\frac{1}{2}$
