Question

Solve the following proportion for the unknown variable: 15/d = 24/40

Answer 1

Answer:
d = 25

Explanation:
To get the value of d, we will need to isolate the d on one side of the equation.

This can be done as follows:
$\frac{15}{d} = \frac{24}{40}$

First, we will do cross multiplication as follows:
40*15 = 24*d
600 = 24d

Then, we will isolate the d as follows:
24d = 600
$\frac{24d}{24} = \frac{600}{24}$

d = 25

Hope this helps :)

Answer 2

Answer:

The unknown variable d is, 25

Step-by-step explanation:

Proportion states that two ratios or fractions are equal.

Solve for d:

$\frac{15}{d} = \frac{24}{40}$

By cross multiply we have;

$600 = 24d$

Divide both sides by 24 we have;

$\frac{600}{24} = d$

Simplify:

25 = d

or

d = 25

therefore, the unknown variable d is, 25.
