Xiao Ming is now 15 yearsold, his sister is 8 years old, and his father is 46 years old. When Xiao Ming was half his father's age, how old was his sister?

Your question is worded improperly.....

I will assume you want to know sis age when xing becomes half his father's age at the time ...in the future

15+x = 1/2 (46+x) where x is th years from now when xing reaches 1/2 father's age

.5x - 8

x = 16 more years 8+16 = sis age = 24 y/o
