Question 1 Report
(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.
