00:43 Always solve multiplication and division before addition and subtraction
00:50 And this is the solution to the question

Step-by-Step Solution

We'll use the distributive property and multiply 33 by each term in the parentheses:

(13×33)+(91×33)= (\frac{1}{3}\times33)+(\frac{9}{1}\times33)=

Let's solve the left parentheses. Remember that:

33=331 33=\frac{33}{1}

13×331=1×333×1=333 \frac{1}{3}\times\frac{33}{1}=\frac{1\times33}{3\times1}=\frac{33}{3}

Now let's address the right parentheses, where we'll break down 33 into a smaller multiplication exercise that will help us later with reduction:

(911×33)=(911×11×3) (\frac{9}{11}\times33)=(\frac{9}{11}\times11\times3)

Now we'll reduce the 11 in the numerator and the 11 in the multiplication exercise and get:

333+9×3= \frac{33}{3}+9\times3=

Let's solve the fraction:

333=11 \frac{33}{3}=11

Now we'll get the exercise:

11+(9×3)= 11+(9\times3)=

According to the order of operations, we'll solve what's in the parentheses and get:

11+27=38 11+27=38

Answer
