If x is the fourth proportional of 48, 72 and 108, what is the value of x?

🔑 Key Points
→ Given:
1st Proportional(a) = 48
2nd Proportional(b) = 72
3rd Proportional(c) = 108
→ Formula Used:
4th Proportional(d) = (b x c)/a

→ Calculations:
According to the formula,
⇒ 4th Proportional(d) = (b x c)/a = (72 x 108)/48 = 162
⇒ Hence, The fourth proportion is 162.
