Question

The difference of 5.76 bar and 2.3bar

Answer 1

Answer:

340/99

Step-by-step explanation:

5.76 bar

let x= 5.76 bar. (1)

multiplying both sides by 100

100x=576767676------×100

or100x=576.76 bar. (2)

equation (2) - equation (1)

100x=576.76 bar

- x= 5.76 bar

99x= 571.0

x=571/99. (3)

2.3 bar

let x =2.3 bar. (4)

multiplying both sides by 10

10x=23333------×10

or10x=23.3 bar. (5)

equation (4) - equation (5)

10x=23.3 bar

- x= 2.3 bar

9x=21.0

x=21/9

x=7/3

subtracting equation (5) from (4)

571/99 - 7/3

L.C.M of 3 and 99 is 99

therefore, (571-231)/99

Ans. 340/99

Answer 2

Answer:

Write 5.76 bar as 5 and - 0.76

Similarly 2.3 bar as 2 and - 0.3

Now to get difference,

(5 - 2) and { - 0.76 - (- 0.3 )}

=> 3 and - 0.46

=> 3.46 bar
