Step-by-step explanation:

Answer 2

So the first thing we need to do is set up an equation (using x to represent the number). Then, we'll solve it to get the answer.

Step 1: Translate the word problem into an equation

Word problem: The sum of nine and six-tenths and a number is thirteen and two-tenths.

Equation: $9 \frac{6}{10}$ + x = $13 \frac{2}{10}$

Step 2: Isolate x by subtracting $9 \frac{6}{10}$ from each side

$9 \frac{6}{10}$ + x -  $9 \frac{6}{10}$ = $13 \frac{2}{10}$ -  $9 \frac{6}{10}$

Step 3: The numbers on the left cancel out, leaving x alone

x =  $3 \frac{6}{10}$

Step 4: Convert the answer to decimals

x = 3.6
