$(12\frac{1}{3} *2)+(10\frac{3}{4} *2)\\\\=(\frac{12(3)+1}{3} *2)+(\frac{10(4)+3}{4} *2)\\\\=\frac{37*2}{3} +\frac{43*2}{4} \\\\=\frac{74}{3} +\frac{86}{4} \\\\=\frac{74(4)+86(3)}{3*4} \\\\=\frac{296+258}{12} \\\\=\frac{554}{12}$

Mathematics

Eleven Years

Step-by-step explanation:

Ok, if the mother is 30, then half her age would be 15. Now, if the daughter is 4, you would subtract 15-4, which equals 11.

So the answer is eleven years.

Hope this helped!
