To write "5 is to 1 as 20 is to 4" as a proportion in fractional notation, we can set up the equation:
5/1 = 20/4
Thus, the proportion in fractional notation is 5/1 = 20/4.
To write "5 is to 1 as 20 is to 4" as a proportion in fractional notation, we need to express the ratio of the two pairs of numbers as fractions.
The first pair, 5 is to 1, can be written as 5/1.
The second pair, 20 is to 4, can be written as 20/4.
Therefore, the proportion in fractional notation is:
5/1 = 20/4
To write the proportion "5 is to 1 as 20 is to 4" in fractional notation, you need to convert the ratios into fractions.
First, let's convert the ratio "5 is to 1" into a fraction. The numerator of the fraction represents the first term (5), and the denominator represents the second term (1). So, the fraction for "5 is to 1" is 5/1.
Next, let's convert the ratio "20 is to 4" into a fraction. The numerator represents the first term (20), and the denominator represents the second term (4). So, the fraction for "20 is to 4" is 20/4.
Now, we can set up the proportion by equating the two fractions:
5/1 = 20/4
To simplify the fraction on the right side, we can divide both the numerator and the denominator by the greatest common divisor (GCD) of 20 and 4, which is 4:
5/1 = (20/4) / (4/4)
Simplifying further:
5/1 = 5/1
Therefore, the proportion "5 is to 1 as 20 is to 4" in fractional notation is 5/1 = 20/4.
