Lawrence bought 2/3 pound of roast beef he used 3/4 to make a sandwich how much roast beef did laurence huse for his sandwich

We have to multiply 2/3 pounds by 3/4:

2/3 * 3/4 = 6/12

Then we will divide the numerator and the denominator by 6:

(6 : 6) / (12 : 6) = 1/2 = 0.5

Answer:

Lawrence used 0.5 pound of roast beef for his sandwich.
