To find this answer, we should subtract 2 1/2 from 3 1/4. The simplest way to do this is to turn them into improper fractions, found the least common denominator, and subtract the numerators.
3 1/4=13/4
2 1/2=5/2
The least common multiple is 4, so we should multiply the numerator and denominator of 5/2 by 2.
5/2=10/4
Now we can just subtract the numerators.
13/4-10/4=3/4
Using the math above, we can see that it saves D. 3/4 hours.
The answer is going to be c
Answer and Step-by-step explanation:
2x + 2 is the answer.
If the boy is twice as old, and the sister's age is represented by <em>x</em>, then we multiply 2 to x to represent the boy's age.
Then we add 2 when 2 years pass by.

Let b be the base. Then
b+16=1/2 (6b)
3b=b+16
2b=16
b=8
