✔ 最佳答案
V*(1+10%) = 121V(100% + 10%)=121
V(110)/100 = 121
V = 12100/110
= 1210/11
= 11*11*10/11
=110

V*(1+10%)=121
V*110%=121
V*110%/110%=121/110%
V=121/100*110
V=132
V*110%=121
V*110%/110%=121/110%
V=121/100*110
V=132

V*(1+10%)=121
V*(1.1)=121
V=121/1.1
V=110
驗算:
Put V = 110 into the equation.
L.H.S.= 110*(1+10%)
= 110*1.1
= 121
= R.H.S.
(L.H.S即係left hand side of 果條式,,R.H.S.即係right hand side of 果條式)
V*(1.1)=121
V=121/1.1
V=110
驗算:
Put V = 110 into the equation.
L.H.S.= 110*(1+10%)
= 110*1.1
= 121
= R.H.S.
(L.H.S即係left hand side of 果條式,,R.H.S.即係right hand side of 果條式)
