Question

express p/q form where pans q are integers and q≠0
1. 0.7
2. 0.54​

Answer 1

Answer:

Fist method

1. 0.7

= 0.7/1

= 0.7×10/1×10

= 7/10

2. 0.54

= 0.54/1

= 0.54×100/1×100

= 54/100

Second method

1. Let,

x = 0.7 .....(1)

So, 10x = 7 .......(2)

(2)-(1)

10x-x = 7- 0.7

9x = 6.3

x = 6.3/9

x = 63/90

2. Let,

x = 0.54 ........(1)

So, 100x = 54 .............(2)

(2)- (1)

100x-x = 54 - 0.54

99x = 53.46

x = 53.46/99

x = 5346/9900
