Solve the following proportion for the unknown variable: 15/d = 24/40
Pavel [41]
<span><u><em>Answer:</em></u>
d = 25

<u><em>Explanation:</em></u>
To get the value of d, we will need to isolate the d on one side of the equation.

<u>This can be done as follows:</u>
</span>\frac{15}{d} =  \frac{24}{40}<span>

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

<u>Then, we will isolate the d as follows:</u>
24d = 600
</span>\frac{24d}{24} =  \frac{600}{24}
<span>
d = 25

Hope this helps :)</span>
