Answer:
B) 1/2 pound
Step-by-step explanation:
Lawrence bought 2/3 pound of roast beef.
He used 3/4 of it to make a sandwich.
The amount of beef that he used for his sandwich is calculated as:
3/4 of 2/3 pounds of roast beef
3/4 × 2/3
= 6/12 pound
= 1/2 pound
Option B is the correct Option.
128
Billy has 55 stamps and his brother Tommy has 73. Add 73 and 55 together. 55+73=128
20 and -20
20^2 = 400
(-20)^2=400 since two negative is positive
