To write "5 is to 1 as 20 is to 4" as a proportion in fractional notation, you would express it as:
\( \frac{5}{1} = \frac{20}{4} \)
To write 5 is to 1 as 20 is to 4 as a proportion in fractional notation, you need to compare the first pair of numbers to the second pair of numbers.
In this case, the first pair is 5 and 1, and the second pair is 20 and 4. To express these proportions in fractional notation, you need to use the format "start fraction a over b end fraction equals start fraction c over d end fraction".
Comparing 5 to 1, you write it as "start fraction 5 over 1 end fraction". Comparing 20 to 4, you write it as "start fraction 20 over 4 end fraction".
Therefore, the correct proportion in fractional notation is "start fraction 5 over 1 end fraction equals start fraction 20 over 4 end fraction".
