Question
Find the quotient, when the mean proportional of 7(1/2)
and 245 is divided by an even prime number.Solution
Convert 7(1/2) to improper fraction:
7(1/2) = 15/2
Mean proportional of 15/2 and 245 = √[(15/2) × 245]
= √[(15 × 245) / 2]
= √[3675 / 2]
= √1837.5
Now divide by the only even prime number, 2:
Quotient = (√1837.5) ÷ 2 = 21.4325
