Question

Express the decimal number in the form p/qwhere p and q are integer and q is not equal to zero 1) 0.74 bar
​

Answer 1

Answer:

Step-by-step explanation:

let x = 0.7444... (1)

multiply (1) by 10

10 x = 7.444... (2)

subtract (1) from (2)

10x-x = 7.444... -  0.7444...

9x = 6.7

x = 6.7/9

Answer 2

Answer:

(1)0.74 bar = 7/9

Step-by-step explanation:

(1) 0.74 bar = 0.7444

Let X= 0.7444...                 (1)

Multiply by 10 on both sides

10X = 10×0.7444...

10X= 7.444…                     (2)

On subtracting equation 1 from equation 2

10X- X =  7.444... - 0.7444...

After Substracting, we get

9X = 7

divide both sides by 9

9X/9 = 7/9

i.e

X = 7/9

Hence , 0.74 bar = 7/9
