A caterer prepared a turkey that weighed 22 1/2 pounds.Each serving of the turkey will be 1/3 pound.How many whole servings will the turkey provide A caterer prepared a turey that weighed 22 1/2 pounds.Each serving of turkey will be 1/3 pound.How many whole servings will the turkey provide

Answer:

67 servings

Step-by-step explanation:

Total # of lbs divided by # of lbs per serving = # of servings

22 1/2 / 1/3

22 1/2 = (22*2+1)/2 = 45/2

To divide by a fraction, multiply by its reciprocal (flipped)

45/2 * 3/1 = 135/2 = 67 1/2

It asks for whole servings, and 1/2 is not part of whole.

1/2 1/2 1/2 1/3

The sum of three times a number b and 33 is at least 35

I love these problems, because it's just about reading the question. All you need to do is break it down. What do we know the "sum of" something is? We know that it means addition. What are we adding? "three times a number b and 33". Well, how can we express "three times b"? 3b! Right! Well, we know we're adding that to 33, so you're almost done. Right now you should have 3b+33. And what is 3b+33? at least 33. How can we express "at least"? >=, greater than or equal to, right! Finally, we have our answer. 3b+33>=35.

B.2NaCl → 2Na + Cl2

C. HCl + NaOH → NaCl + H2O

D. MgI2 + Cl2 → MgCl2 + I2

I think that would be the first one A.
