2 + 2/3 = 2×2 × 2/33 + 3/8 = 3×3 × 3/84 + 4/15 = 4×4 × 4/15若 10 + a/b = 10×10 × a/b则 a+b=?
2 + 2/3 = 2×2 × 2/3
3 + 3/8 = 3×3 × 3/8
4 + 4/15 = 4×4 × 4/15
若 10 + a/b = 10×10 × a/b
则 a+b=?

2 + 2/3 = 2×2 × 2/33 + 3/8 = 3×3 × 3/84 + 4/15 = 4×4 × 4/15若 10 + a/b = 10×10 × a/b则 a+b=?
a=10,b=99,a+b=109.通过前3个式子可以发现b=a*a-1.而a等于前边那个数.
