### Ratio and Proportion Quiz Question.

# Mathematics Quizzes Ratio and Proportion

**Question:**

Let x, y, and z be positive integers such that y is a multiple of x and z. All of the following statements are true except for:

**Option A):**

X is a factor of y**Option B):**

X.z is a factor of y**Option C):**

X divides evenly into y.z**Option D):**

Y.z is a multiple of x**Option E):**

Z divides evenly into y

**Correct Answer is Option B):**

X.z is a factor of y

**Explanation:**

Note that this item asks for the choice that is NOT true.

We know y is a multiple of x and z. That means y times any number is also a multiple of x, so choice A must be true.

Also, because we know y is a multiple of x and z, this means that x and z divide evenly into y, so choices B, D and E

are true.

The process of elimination leaves choice C.

Use an example to check this. Let x = 3, y = 12, and z = 6. y is a multiple of x and z, but x z = 18 is not a multiple

of y = 12.
