Answer 2

Answer:

the third proportion 343/27 or 12.70

Step-by-step explanation:

3/7 and 7/3 the third propotional of two numbers a and b is defined to be that number c

such that a:b=b:c

so,here we want to find a number c.

therefore

a = 3/7, b = 7/3, c = c

a:b = b:c

3/7:7/3 = 7/3:c

(3/7)/(7/3) = (7/3)/c

3/7*3/7 = 7/3c

9/49 = 7/3c

c = 7/3 * 49/9

c = 343/27 or 12.70
