I think of a number and add one fourth of it to half of it and the result is twelve. What is the number I thought of?

belka [17]

Suppose that the number u were thinking about is x thus :

$\frac{1}{4} x + \frac{1}{2} x = 12 \\$

Multiply both sides by 4

$4 \times ( \frac{1}{4} x + \frac{1}{2} x) = 4 \times 12 \\$

$x + 2x = 48$

$3x = 48$

Divide both sides by 3

$\frac{3x}{3} = \frac{48}{3 } \\$

$x = 16$

n200080 [17]

Answer:

C. Dividing by 4 is the inverse of multiplying by 4.

Step-by-step explanation:

We have been given 4 options. We are asked to choose the option that represents inverse relationship.

We know that inverse of addition is subtraction and vice versa.

We also know that inverse of multiplication is division and inverse of division is multiplication.

Upon looking at our given choices, we can see that option C is the correct choice because we are multiplying and dividing by same number 4. Upon dividing and multiplying a quantity by 4, we will get the same quantity.

$\frac{4\cdot a}{4}=a$

Therefore, dividing by 4 is the inverse of multiplying by 4.
