Question

2. Express as a rational number in the form of
(1) 0.5333
(ii) 0.21042104
(iii) 2.24689689​

Answer 1

Answer:

(i) 0.533(3 par bar)

let x=0.533(3par bar)

multiply both by 10

10x=5.33(3par bar)

10x=4.8+0.533(3 par bar)

10x=4.8+x

10x-x=4.8

9x=4.8

x=4.8/9

x=48/90

(ii) 0.2104(2104 par bar)

let x=0.2104

multiply both by 10000

10000x=2104.2104.....

10000x=2104+0.2104....

10000x=2104+x

10000x-x=2104

9999x=2104

x=2104/9999

(iii)2.24689(689 par bar)

let x=2.24689....

multiply both by 1000

1000x=2246.89689...

1000x=2244.65+3.24689....

1000x=2244.65+x

1000x-x=2244.65

999x=2244.65

x=224465/99900
