Answer 2

Answer:

If x, y and z are in proportion, then the correct option will be x : y : : y : z.

Step-by-step explanation:

A proportion is an equation in which two ratios are set equal to each other.

If 3 numbers are in proportion to each other then their ratios should be equal to one another.

For example:

If 1, 2 and 4 are in proportion then it should be true that:

1 : 2 = 2 : 4

This can be written as:

1 / 2 = 2 / 4

1 / 2 = 1 / 2

So, with this, we get that if x, y and z are in proportion, then it must be true that:

x : y = y : z

which can also be written as:

x : y : : y : z

Therefore, we get that if x, y and z are in proportion, then the correct option will be x : y : : y : z.
