Answer:
632
Step-by-step explanation:
So we can define decreasing x% in two ways: we can define 20% off as 80% of the original value, or we can define subtracting 20% from the original value, and both representations are useful.
In this case it's more useful to define 20% as subtracting 20%, from the original value. The reason for this, is because since we're subtracting 20% of the original value, we then know that 126.40 is 20% the original value.
So to find x% of some value, you generally use the following equation: 
where A=original amount, and x is the percent. This equation is simply converting the x% to a decimal value. Since 126.40 is 20%, we can derive the following equation.
We can solve for A, by dividing by 0.20
It's also important to note, you didn't really have to set up this entire equation, since you know that the 126.40 is 20%, you simply could've multiplied by 5, since 20% is really just 1/5 of the entire value, so get the entire value, or original value you multiply by 5
<span>Let us first make the units same (like terms). Convert 2 feet into inches since the other term is already in inches. It is 24 inches.
Now the ratio is 18 inches to 24 inches.
To convert a ratio into a fraction, simply use the first number as the numerator and the second number as the denominator. So the fraction is 18/24. There are common factors in 18 and 24 which can divide both these numbers. 2 is a common factor and when both the numerator and denominator are divided by 2, the fraction becomes 9/12. The next common factor is 3. Divide both the numbers by 3. Now the fraction becomes 3/4. Since there are no more common factors, the fraction is in its lowest form.</span>
