Answer:
simple just divide it by finding the reciprocal for the second number
ex: 2/4=4/2
then multiply
Step-by-step explanation:
f = (f1 f2) / (f1 + f2)
f(f1 + f2) = f1 f2
f f 1 + f f 2 = f1 f 2
f1 f2 - f f2 = f f1
f2 (f1 - f) = f f1
f2 = (f f1) / (f1 - f) <==== solution
X = 13/2 or 6 1/2. Hope this helps!
Answer:
£ 21552.13
Step-by-step explanation:
