Question

0.001 in number system class 9

Answer 1

0.001  is to be expressed  as  a ratio  p / q.

we check how many digits are present after the decimal.  There are 3.  So  we take 1 and put 3 zeros  after it.  so we get  1 000.

Then we see the number after the decimal :  it is 001  or  1.

we write now,      1 / 1000   .  this is the ratio you want.
=============================

suppose  you  have   0.02303

number of digits after decimal:  5 
so put 1 and 5 zeros after;    1 00 000
write the number after decimal:    02303   or  2303

the ratio :  2303 / 100 000

Answer 2

Answer:

0.001

Step-by-step explanation:

0.001 is a rational number and can be written in the form p/q.

To get it in this form, we multiply both numerator and denomintaor by 1000.

Like so-

0.001*1000/1*1000

= 1/1000

Note- To determine which power of 10 to use, look at the number of decimal places. Here 3 places are there, so I have used 1000 (which is 10^3).

Hope this answer helps!
