Answer:
7 pounds 3 ounces
Step-by-step explanation:
There are 16 ounces in a pound. In order to convert ounces to pounds, we need to see how many 16s fit into 115 (how many full pounds can be made with 115 ounces) and add the remainder as ounces. To do this we can do long division (which gives us 7 remainder 3), or we can divide 115 by 16 (=7.1875) and convert the decimal places to ounces by multiplying 0.1875 pounds (the remainder) by 16 (as there are 16 ounces in pound) which gives us 3 ounces.
So 115 ounces is equal to 7 pounds and 3 ounces.

Answer:
A. 30
B. 6
Step-by-step explanation:
We'll use P for Penny's age and B for Benny's age. When Penny is 24, Benny will be 1.25 her age. Thus:
B = 1.25 * 24
(benny is 25% older than her)
So Benny's age then will be 1.25 * 24 = 30.
When Benny is 30, Penny will be 24. This means that he is older than her by 6 years. Think about it for a second: Benny will <em>always</em> be 6 years older than her. You can write that as:
B = P + 6
If Benny is 12 years old now,
12 = P + 6
Subtract 6 from both sides and you get
6 = P
or P = 6
Penny is 6 years old when Benny is 12.
