Answer:
To find the number of nickels in $22, we need to first convert the amount of money from dollars to cents and then divide this number by the value of a nickel in cents. Since 1 dollar is equal to 100 cents, we can convert $22 to 2200 cents.
Next, we need to find the value of a nickel in cents. Since a nickel is worth 5 cents, the value of a nickel in cents is 0.05 * 100 = 5 cents.
Finally, we can divide the total number of cents by the value of a nickel in cents to find the number of nickels:
2200 cents / 5 cents/nickel = 440 nickels
Therefore, there are 440 nickels in $22. Solving the equation 22 ÷ 0.05 gives the same result.
