Question

b) Evaluate:
i)(12)10 = (X)2
ii)(347)8= (X)10
iii)(896)16= (X)8
iv)(100)10= (X)2
​

Answer 1

Answer:

i) (12)10=(×)2

12×10= 120

120=(×)2

120/2=×

60=×

therefore ×=60

(12)10=(60)2

120=120

ii) (347)8 = (×)10

2776= (×)10

2776/10=×

277.6=×

therefore ×=277.6

(347)8 = (277.6)10

2776 = 2776

iii) (896)16 = (×)8

896×16 = (×)8

14336 = (×)8

× = 14336÷8

× = 1792

therefore × = 1792

(896)16 = (1792)8

14336 = 14336

iv) (100)10 = (×)2

100×10 = (×)2

1000 = (×)2

× = 1000÷2

× = 500

therefore × = 500

(100)10 = (500)2

1000 = 1000
