Known x, y, Z are real numbers, if x + y + Z ≠ 0, a = x / x + y, B = Y / Z + X, C = Z / x + y, find the value of a / A + 1, B / B + 1, C / C + 1, please answer in detail!

Known x, y, Z are real numbers, if x + y + Z ≠ 0, a = x / x + y, B = Y / Z + X, C = Z / x + y, find the value of a / A + 1, B / B + 1, C / C + 1, please answer in detail!

A = x / x + y? Should be a = x / y + Z!
a/a+1=(X/(Y+Z))/((X/(Y+Z))+1)=X/X+Y+Z
b/b+1=Y/X+Y+Z
c/c+1=Z/X+Y+Z

For positive integers a, B, C (a ≤ B ≤ C) and real numbers x, y, Z, W, if a ^ x = B ^ y = C ^ z = 70 ^ W, and 1 / x + 1 / y + 1 / z = 1 / W, find the value of a, B, C
emergency

a^x=70^w
a=70^(w/x)
Similarly, B = 70 ^ (w / y)
c=70^(w/z)
abc=70^(w/x+w/y+w/z)=70^w(1/x+1/y+1/z)=70=2*5*7
a=2,b=5,c=7

Given that ABCD is a positive real number and a / b > C / D, then M = B / A + B - D / C + D is a.m > 0 B.M ≥ 0 C.M

Because a / b > C / D
So: (a + b) / b > (c + D) d
Take the reciprocal at the same time
b(a+b)
