First number = 10
Second number = 12
Third number = 15
Formula Used:
If a, b, c, and d are in proportion, then \(\frac{a}{b} = \frac{c}{d} . \)Fourth proportion, d = \(\frac{b \times c}{a}\)
Calculation:
Here, a = 10, b = 12, and c = 15.
Fourth proportion, d =\( \frac{b \times c}{a}\)
⇒ d = \( \frac{12 \times 15}{10}\)
⇒ d = \(\frac{180}{10}\)
⇒ d = 18
The fourth proportion to 10, 12, and 15 is 18.
