Kate has 1 dime, 4 nickels, and 8 pennies. write kate’s total amount as a fraction in terms of a dollar.

Review:
dime = 10 cents or $0.1
nickel = 5 cents or $0.05
penny = 1 cent or $0.01

now, you have 1 dime = 10 cents 
and 4 nickels = 20 cents 
and 8 pennies = 8 cents
total is 38 cents
100 cents is a dollar

Total amount as a fraction in terms of a dollar is 38/100 

Hope this helps :)
