(a) Copy and complete the following table for multiplication modulo 11.

$\otimes$	1	5	9	10
1	1	5	9	10
5	5
9	9
10	10

Use the table to : (i) evaluate $(9\otimes 5)\otimes (10\otimes 10)$;
(ii) find the truth set of :(1) $10\otimes m=2$; (2) $n\otimes n=4$
(b) When a fraction is reduced to its lowest term, it is equal to $\frac{3}{4}$. The numerator of the fraction when doubled would be 34 greater than the denominator. Find the fraction.
