The answer is 70 because angle CGA is a 90° angle and it is split into two. so if one part of it is 20°. 90-20 equals 70°
Step 1.) Set up the equation
28 %
---- = ------
40 100
Step 2.) Multiply the cross products
2800 = 40x
-------- ------
40 40
70% = x
36 liters
8 • 4 (8 liters for 4 cars)
2 • 2 (2 liters spilled for 2 sets of 2 cars)
21.25% as a fraction is a pretty easy, but very complex problem to solve. The very first thing I would do is turn the percent to a decimal by simply moving the decimal two spaces to the left, or by dividing by 100. This makes it a lot easier.
21.25% = 0.2125
From here, the decimal reads: two thousand, one hundred and twenty five ten thousandths.
So as a fraction, it is 2125/10000.
Next, we’ll need to reduce this. I would start by dividing by twenty five:
85/400
Divide by five:
17/80
Therefore, your answer is 17/80.
