Please help me with these. You'll be respected forever. I really need help with these.

a) please write 5.(6) % as a common fraction or a mixed number. The (6) is repeated.

b) Eight pounds of peanuts cost $24.00. Six pounds of walnuts cost half as much. Which is more expensive and by how much?

c) Eight pounds of peanuts cost $24.00. Six pounds of walnuts cost half as much. How much will Jim pay for 3 lbs of peanuts and 6 lbs of walnuts?

d) Write “four hundred dollars and seventy two cents”... as a fraction (and then reduce).

I will give brainliest if correct. Thanks.
