First, we have to find how many times 10 goes into 15.
We can divide 15 by 10, and we will see that 10 goes into 15 1 whole time, with 5/10 left over.
Now, we can simplify!
In order to simplify, we have to find the GCF (greatest common factor) of 5 and 10. Let's list out the factors (the numbers that can be divided into 5 and 10)
1*5
1*10
2*5
The largest factor, as we can see, is 5! Let's dicide 5/10 by 5.
5/5=1
10/5=2
So, 5/10 simplifies to 1/2, and, if we bring down the whole number we found before, 15/10 is equal to 1 and 1/2! :)
We can check this answer by multiplying the whole number, 1, by the denominator, (the bottom number of a fraction) 2, and adding the numerator, (the top number of a fraction), 1.
1*2=2
2+1=3
Keep the denominator as 2.
The improper fraction is 3/2, which is equivalent to 15/10 (multiply 3/2 by 5 to see)!
So, our answer is 1 1/2.
I hope I helped! :)

Answer with negative exponent = 
===========================================================
Explanation:
The rule we use is

If we multiply two exponential expressions with the same base, then we add the exponents.
The base for each is 5. The exponents 4 and -7 add to -3.
This means

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.
So, 
Answer:
mass of solution = mass of sugar / concentration
mass of water = mass of solution - mass of sugar
Answers for 50%
mass of solution = 0.5 lbs / 50% = 0.5 lbs / 0.5 = 1 lbs syrup
mass of water = 1 lbs - 0.5 lbs = 0.5 lbs of water
Answers for 5%
mass of solution = 0.5 lbs / 0.05 = 10 lbs syrup
mass of water = 10 lbs - 0.5 lbs = 9.5 lbs of water
Answers for 75%
mass of solution = 0.5 lbs / 0.75 = 0.6667 lbs syrup
mass of water = 0.6667 lbs - 0.5 lbs = 0.1667 lbs of water
Answers for 1.5%
mass of solution = 0.5 lbs / 0.015 = 33.33 lbs syrup
mass of water = 33.33 lbs - 0.5 lbs = 32.83 lbs of water
