Density of water = 1000 kg/m^3
1 m^3 = 1000 litres
Therefore,
1000 kg/1000 l => 1 kg/l => 1000 g/l
Then, 300 g of water = 300/1000 l = 0.3 l
The concentration of the syrup = mass/amount of water = 60 g/0.3 l = 200 g/l

Answer: 1/4</h3>
=================================================
Explanation:
Let's say this school has 1000 students.
5/8 of that amount is (5/8)*1000 = 625. There are 625 students who play sports.
Then we take 2/5 of this to get (2/5)*625 = 250 to represent the number of people who play soccer.
The last step is to divide that result over the original number of students. Reduce as much as possible.
250/1000 = 25/100 = 1/4
Therefore, 1/4 of all the students play soccer
Answer: ∡RSQ and ∡TSQ
Supplementary angles are angles that add up to 180 degrees. We can see in the picture that both angles are located on the same line, and no other angles are involved, so they must equal 180.
We can also use the process of elimination:
- ∡RSQ and ∡UVS are congruent because they are consecutive angles.
- ∡RSQ and ∡WVX are also congruent because they are alternate exterior angles.
- ∡RSQ and ∡TSV are also congruent because they are vertical angles.
