I am helping my sister with her hw. They are to write the meaning of a group of words or in that case idioms. What does BET DOLLARS TO DOUGHNUTS, and GETAROUN TO CALLING mean?

Please help!!!!
Thank you!!! :-)

BET DOLLARS TO DOUGHNUTS = you're sure of the answer

The second one makes no sense. Please proofread and repost.

The first one is in the D's and the second is in the G's.

ok sorry the second one was supposed to be GET AROUND TO CALLING sorry i was typing to fast.

oh and writeacher, sorry if i say this, but your answer makes no sense. I looked at the website and it explained what idioms meant

Saranghae -- you didn't investigate that site thoroughly.

As Writeacher indicated, I clicked on D -- went to the second page of D's and found this.

"Dollars for doughnuts
(USA) If something is dollars for doughnuts, it is a sure bet or certainty."

Do the same for G.

oh ok thank you!!! i guess i really didn't investigate the site srry

You're welcome. :-)
