1) 3 \frac{1}{3}

in improper fraction = 3x3+1 = \frac{10}{3}

multiplicative inverse = \frac{3}{10}

2) as sum of exterior angle is always 360 , measure of each exterior angle is \frac{360}{15}

= 24 degree

3) sorry i do not know what is unbiased  but the prime numbers in a normal dice are 2,3,5  so probability in normal dice = \frac{3}{6}  

simpified = \frac{1}{2}

4) no it wont be a perfect square because in square roots the number of zeroes should always be even to make it perfect

5) 11 cube = 11 x 11 x 11 = 1331

6) price = 170 rupees

SECTION B

7) \frac{5}{12}  + \frac{-3}{12}   = \frac{2}{12}

simplified = \frac{1}{6}

\frac{7}{5}  x  \frac{1}{6}  = \frac{7}{30}

8) let the integers be x , x+1, x+2

so

x + x+1 + x+2 = 60

3x  + 3 = 60

3x = 60-3

3x = 57

x =  \frac{57}{3}  = 19

x = 19

so integers are :

x = 19

x+1 = 19 + 1 =20

x+2 = 19 + 2 =21

19,20,21

9) the question is incomplete we need the measure of angle q to find the answer

10) a )  \frac{9}{10}

     b)   \frac{5}{10}

11) triplets = 2m , m^{2} + 1 , m^{2} - 1

let 2m = 8

m = 8 divided by 2 = 4

m^{2} + 1 = 4^{2} + 1 = 16 + 1 = 17

m^{2} - 1 = 4^{2} - 1 = 16 - 1 = 15

triplets = 8,17,16

in which 8 is the smallest


hope it helps
