Question

1) Express 1.45 bar on 45
in the form of p/q
​

Answer 1

1.45 bar

Let X = 1.45

Then X = 1.454545........(1)

multiply equation 1 by 100 we get,

100X = 145.454545......(2)

Subtract equation (1) from equation (2) we get,

100X = 145.454545

X. = 1.454545

__________________

99X = 144

X = 144/99 = 48/33 = 16/11

Hence,

1.45 bar is in the form of 16/11 which is in the form of P/Q.

Answer 2

Answer:

x=212/9

Step-by-step explanation:

Let x= 1.45 bar

x= (1.4545...........)________eqn 1

x*100=(1.4545........)*100

100x=(145.4545...........)_____eqn 2

Subtract eqn 1 from eqn 2

100x-x= (145.4545.........)*(1.4545.........)

99x= 212

x= 212/99
