Question

I'm writing an essay. One of my sentence goes like this "... to attack the problems in hand..." I wonder is it "in hand" or "at hand"? Also, should I use singular or plural (i.e. hand or hands)? Thank you.

Answer 1

at hand, singular.

Problems is plural.

to attack is a noun...singular.

make sure your verb matches.  

Answer 2

"...to attack the problems at hand."

"in hand" is incorrect.

"hands" is incorrect.
