We are asked to determine the unit multipliers in order for us to convert 630 square yards to into square inches. Well, first we need to convert square yards to square feet and secondly, we convert square feet to square inches.
square yards -> square feet -> square inches
We also take note the following:
1 yard = 3 feet
1 foot = 12 inches
The solution in converting the unit is shown below:
630 yards² * (3 feet / 1 yard)² = 5670 feet²
5670 feet² * (12 inches / 1 foot)² = 816,480 inches²
The answer is 816,480 inches².
Just plug it into a calculator and you would get 400
Answer: 
<u>Use the slope formula</u>
<u>Note</u>
You need to calculate 12% of 800.
To find a percent of a number, multiply the percent by the number.
Change the percent into a decimal by dividing the percent by 100 (move the decimal point of the percent two places to the left.)
12% of 800 =
= 12% * 800
= 0.12 * 800
= 96
Answer: 96 students
