class 9 math question​

Answer 1

Answer:

a) x= 32.12(35)

100x=3212.(35)

10000x=321235.(35)

9900x=318023

therefore x= 318023/9900= 32.12

Answer 2

Answer:

i)  318023/9900

ii) 235/999

Step-by-step explanation:

i)

32.1235 (bar on 35) = 32.12353535....

x = 32.1235 (bar on 35)

x = 32.123535353535..... --->1

100x = 3212.3535353535....... --->2 ( multiply by 100)

10000x = 321235.35353535..... ------> 3( multiply 100 again)

9900x = 318023

x = 318023/9900

ii)

0.235bar = 0.235235235235.......

Let x = 0.235bar

x =0.235235235235235...... --------> 1

1000x =235.235235235.........-------->2 ( as 0.235 as 3 dights repeating)

999x - 235 ( 2-1)

x = 235/999

∴ 0.235bar = 235/999
