2/3n=7/8 what does it equal and how do i solve it

There is 1 and 5/16th of a pound of cashews in the bag.
In order to solve for n one needs to get rid of 2/3 by multiplying it by 3/2 on both sides (therefore canceling the 2/3 by the n (technically 1n but that is the same as just saying n). multiply 7/8 by 3/2 equaling (must do same on both side) n= 21/16 which can be reduced to 1 and 5/15 a pound. Therefore Bryce used 1 and 5/16th a pound of cashews at the party.

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
