How do you work out that. 9 is the largest number please explain in detail.

Folake said: (Sep 8, 2011)  
Please explain how do you get 9 ?

Sharmila Banu said: (Sep 17, 2011)  
9/1000*1/100=9/10=0.9

Sowjanya said: (Oct 28, 2011)  
Sharmila is right yar.

Yuvaraj said: (Dec 10, 2011)  
@ Sharmila Banu,
You should either put bracket at apropriate places like
(9/(1000*1/100)) else write the equation as
(9/1000)/(1/100)

.009/.01=.009/.01*100/100

.900/1=.9/1=.9

Here question is (.009)/?=(.01)
we can rearrange this as (0.009)/0.1=?
mulitiply numerator and denominator by 1000. then we get
9/(10)=.9
hence the answer is 0.9

Sona said: (Mar 25, 2012)  
0.009 = 9/1000 and 0.01 = 1/100 so put values

9/1000
= -----------
1/100

so 9/1000 * 100/1

= 9/10

= 0.9

Anu said: (Jun 15, 2012)  
Why are we multiplying it with 1000 ?

Keerthi said: (Aug 20, 2012)  
Multiply both side by 1000 since .009 has three digit after its decimal
.009*1000/x=.01*1000
9/x=10
9/.9=10
ans=0.9

Manikandan said: (Aug 29, 2013)  
0.009/? = 0.01.

Let 0.009/A = 0.01.

A = 0.009/0.01.

A = 0.009*1000/0.01*1000.

= 9.000/10.000.

= 0.9.

Hello guys.

.009/x = .01
.009 = .01x

9/1000 = 1/100 x
900/1000 = x

9/10 = x
x = .9

Harish said: (Jul 1, 2014)  
0.009/? = 0.01.

x = 0.009/0.01.
= 0.9*10^2/1*10^2.
= 0.9*10^2-2/1.
= 0.9.

Murali said: (Jul 15, 2014)  
0.009/0.01.
Now divide and multiply with 1000.
So you will get 9/10.

So now convert into decimal.
0.9 is the answer.

Sudhakar said: (Jul 9, 2015)  
Let 0.009/A = 0.01.

=> A = 0.009/0.01.

=> A = 0.9.

Fazil said: (Aug 6, 2015)  
How its possible?

Suryakant said: (Oct 21, 2015)  
Answer should be 0.9 because 0.009/0.09 = 0.1.

Hence answer is 0.9.

Suraj said: (Aug 12, 2016)  
0.009 divided by option [B]: 0.09 >> gives 0.1.

Chandu said: (Sep 14, 2016)  
.0009/.09 = 0.1. It is also correct.

Kamal said: (Sep 27, 2016)  
x = .009/.01 * 100/100 = 0.9/1 = 0.9.

Sindhu Atmuri said: (Nov 25, 2016)  
.009/.01=.9 (zeros are cancelled) is it a write method to calculate?

Raja Kumar said: (Jun 1, 2017)  
0.009/x = 0.01,
x = 0.009/0.01 = 0.9 answer.

Ronaldo said: (Jul 13, 2017)  
Thanks @Sharmila.

Nagaraju said: (Jul 21, 2017)  
(0.009/?)=0.01.
(0.009*100/?)=0.01*100.
0.9/?=1,
?=0.9.

Ram said: (Apr 10, 2019)  
The answer will be 0.9.
