Final answer:
The ratio of 2 nickels to 5 dollars is 1/50 when both are converted into pennies and the fractional notation is simplified to its lowest terms.
Step-by-step explanation:
The question asks to write the ratio in fractional notation in lowest terms for the comparison of 2 nickels to 5 dollars. To correctly write this ratio, we must convert both amounts to the same unit of currency. Since there are 100 pennies in one dollar, 5 dollars would equal 500 pennies. A nickel, which is 5 pennies, can also be easily expressed in pennies.
So, we have the ratio of 2 nickels (which is 10 pennies) to 500 pennies. The ratio in fractional form is then:
10 pennies / 500 pennies = 1/50
Thus, the ratio of 2 nickels to 5 dollars in fractional notation in lowest terms is 1/50.
