Answer 1

X = 0.357 bar on 7

100x = 35.7 bar on 7 .....(i)

1000x = 357.7 bar on 7 ......(ii)

900x = 322

x = 322/900

x= 161/450

Hope it helps you

Answer 2

Let x be 0.35777.....

On multiplying by 100

100x=35.777....

100x=35+0.777......eq1

Let a =0.777.....eq2

On multiplying both side by 10

10a=7.777.....eq3

On subtracting eq2 from eq3

10a–a=7.777–0.777

9a=7

a=7/9

From eq1

100x=35+0.777.....

100x=35+7/9

x=35+7/900

31507/900
