Final answer:
To solve the proportion 0.75:n = 5:8, set the two ratios equal to each other and solve for n.
Step-by-step explanation:
To solve the proportion 0.75:n = 5:8, we can set the two ratios equal to each other:
0.75/n = 5/8
Next, we can cross-multiply to solve for n:
0.75 * 8 = 5 * n
6 = 5n
Lastly, we can divide both sides of the equation by 5 to find the value of n:
n = 6/5
Therefore, n is equal to 1.2.
