Aquarium 1 will hold 5 small fish for every 10 gallons of water. If there are 200 gallons in the tank, you can sent up a proportion:
5 small fish/10 gallons = x small fish/ 200 gallons
if you cross multiply, you get
10x = 200 × 5
10x = 1000
x = 100
100 small fish will be in 200 gallons of water.
Aquarium 2 will hold 8 large fish for every 40 gallons of water. A proportion can also be set up here:
8 large fish/ 40 gallons = x large fish/ 200 gallons
if you cross multiply, you get:
40x = 200 × 8
40x = 1600
x = 40
40 large fish will be in 200 gallons of water.
the ratio of small fish to large fish:
100 small fish: 40 large fish
(both are divisible for 10, and if you divide both of them by ten you get)
10 small fish: 4 large fish
you can reduce again, since both are divisble by 2
5 small fish: 2 large fish
Answer:TRUE
Explanation: Displacement is a change in position of an object or a person starting from where he or she started or where the object was sent from to the final point. If an object or a person returns to the same point as at the point he or she started the person's displacement is ZERO.

<span>There are several principles of democracy. In a democratic society, everyone is
equal. This means that they have the
same rights no matter who they are. The
laws and institutions are based on fairness and impartiality. This means no one
gets preferential treatment. Ideas come from individuals and those ideas are shown
to a council who vote on it. People have
the right to express their ideas in a democratic society. Though the majority holds power, the minority
and absentee members’ rights will be respected.
Whether you are from the majority or minority, you have rights and those
rights allow you to take part in important discussions or events. Systems and procedures in a democratic
society is done in openness where everyone has the right to know the whole
truth. Leaders and officials are chosen
by the people through an election process.
When their term of office ends, they return to civilian life. Power in all
branches of government is shared equally.</span>
