You simply read the table on this one
If you compare table values to answer choices, you can see right away that several don't work. The number of centimeters is greater than the number of inches, so adding to or multiplying the number of centimeters by some number more than 1 will not give you the smalller number that is inches.
While it may work for the first number (5 inches) to add 7.7 to get the first number of centimeters (12.7), you have to know that you can only add like to like. You can only add inches to inches (getting a result of inches), or centimeters to centimeters (getting a result of centimeters). From the point of view of the units involved, it is <em>nonsensical</em> to add a pure number to a number of inches and expect to get a number of centimeters.
So, we're down to the second choice:
- The number of inches is multiplied by 2.54 to find the number of centimeters.
_____
To find the pattern in the table, you can ...
- observe that the inch values differ by 1
- observe that the centimeter values differ by 2.54
- realize that the constant differences mean the relation between inches and centimeters is linear, and that a change in an inch value of 1 inch is multiplied by 2.54 to find the corresponding change in centimeter value.

I don't know what the first step in your problem solving process is supposed to be. In my problem solving process, the first step is always to <em>look at what you are given</em>. The next step is <em>look at what you are being asked for</em>.
The first step is to calculate the total number of pizza slices there are.
We know each slice is 1/8 of the pizza. (think of 1/8 as 1 out of 8 pieces)
This means each pizza has 8 slices.
There are 3 pizzas so there are 8 x 3 = 24 slices total
Next we want to figure how many slices of pizza they ate which will help us figure out how many are left.
They ate 3/4 of the pizza, so in other words only 1/4 of the pizza is left.
In order to figure out how many slices are left, all we need to do is find out what 1/4 of the total number of slices are.
# of slices left = Total number of slices x 1/4 (1/4 of the pizza is left)
# of slices left = 24 x 1/4 = 24÷4 = 6
This means there are 6 slices of pizza left.
The answer is 45 because supplement means the sum of 180 so 180 divided by 4 is 45 and t=45
