What is direct proportion?

• Direct proportion is a relationship between two variables where their ratio is not constant.

• Direct proportion is a relationship between two variables where their ratio is inversely proportional.

• Direct proportion is a relationship between two variables where their ratio is constant.

• Direct proportion is a relationship between two variables where their ratio changes randomly.

In direct proportion, if one quantity increases, what happens to the other quantity?

• Stays the same

• Fluctuates

• Decreases

• Increases

What is the formula to represent direct proportion?

• y = kx^2

• y = k/x

• y = kx, where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.

• y = x + k

What is inverse proportion?

• Inverse proportion is a relationship between two variables in which the product of the two variables is constant.

• Inverse proportion means that as one variable increases, the other variable also increases.

• Inverse proportion is a relationship between two variables in which the sum of the two variables is constant.

• Inverse proportion is a relationship between two variables in which the difference between the two variables is constant.

In inverse proportion, if one quantity increases, what happens to the other quantity?

• The other quantity remains the same.

• The other quantity decreases.

• The other quantity increases.

• The other quantity becomes zero.

What is the formula to represent inverse proportion?

• y = k+x

• y = k*x

• The formula to represent inverse proportion is y = k/x, where y and x are the two variables and k is the constant of proportionality.

• y = k^x

What is partitive proportion?

• Partitive proportion is a type of cloud formation

• Partitive proportion is a type of dance move

• Partitive proportion is a cooking technique

• Partitive proportion is a mathematical concept that compares the parts of a whole to each other.

In partitive proportion, how are the quantities divided?

• The quantities are divided randomly

• The quantities are not divided at all

• The quantities are divided in the same ratio.

• The quantities are divided equally

What is the formula to represent partitive proportion?

• The formula to represent partitive proportion is a/b = c/d

• a + b = c - d

• a * b = c / d

• a - b = c + d

If y is directly proportional to x, and y = 10 when x = 5, what is the value of y when x = 8?

• 12

• 8

• 16

• 20
