Answer:

98.

Step-by-step explanation:

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

You have to do it in order so you can get the correct answer. Do the problem in the parenthesis first. 6 ÷ 3 = 2.

It should look like this:

7² x 2.

Then, do your exponents. 7² is just basically 7 x 7. It equals 49.

Now, it should look like this:

49 x 2. Multiply 49 x 2, and your answer should be 98.

3/9 + 3/27 = ? Adding fractions

RideAnS [48]

$\frac{3}{9}$ + $\frac{3}{27}$ equals $\frac{4}{9}$ .

First, simplify $\frac{3}{9}$ to $\frac{1}{3}$ and also $\frac{3}{27}$ to $\frac{1}{9}$ . Your problem should look like: $\frac{1}{3}$ + $\frac{1}{9}$ .
Second, find the least common denominator of $\frac{1}{3}$ and $\frac{1}{9}$ to get 9.
Third, make the denominators the same as the least common denominator (LCD). Your problem should look like: $\frac{1x3}{3x3}$ + $\frac{1}{9}$ .
Fourth, simplify to get the denominators the same. Your problem should look like: $\frac{3}{9}$ + $\frac{1}{9}$ .
Fifth, join the denominators. Your problem should look like: $\frac{3+1}{9}$ .
Sixth, simplify. Your problem should look like: $\frac{4}{9}$ , which is the answer.
