Solve (9+120)÷3: Order of Operations Division Problem

Question

$\frac{9+120}{3}=$

00:00 Solve

00:03 Let's use the distributive law

00:06 Let's factor 9 into factors 3 and 3

00:10 Let's factor 120 into factors 40 and 3

00:23 Let's split the fraction into two fractions

00:30 Let's simplify what we can

00:38 And this is the solution to the question

In order to simplify our calculation, we first separate the addition exercise into two smaller multiplication exercises:

$\frac{(3\times3)+(40\times3)}{3}=$ We then split the resulting equation into an addition exercise between fractions:

$\frac{3\times3}{3}+\frac{40\times3}{3}=$

Lastly we reduce the 3 in both the numerator and denominator, and obtain:

$3+40=43$
