Hannah buys 2/3 pound of roast beef. she uses 1/4 pound to make a sandwich for lunch. how much roast does she have left?

What we know: Hannah buys 2/3 LB

Uses 1/4 LB

Well, the word "left" tells you that you would have to subtract 1/4 from 2/3. This is when you will have to find out the Least Common Denominator for both fractions.

Now, just subtract:
