3/4 divided by 2
= 3/4/2
= 3/4x2
= 3/8.
Hence, 3/4 divided by 2 is equal to 3/8.
3/8 as a Decimal :
In this we should convert the denominator into 10, 100, 1000, 10000, 100000,... to make it simple.
Now to make 8 into 1000, we multiply numerator and denominator with 125
=>
1/10 as a Decimal :
1 divided into 10 parts of each 0.1.
Therefore, 3/8 = 0.375 and 1/10 = 0.1 in decimals.
Here in decimal means 8th part in 1.
We know that = 0.1
Then,

×1-1 ×1+1 ×2-1 ×2+1 ×3-1
15x3 - 1 = 45 - 1 = 44
Can be easily solved with following formula
= (25.732 - 15.732 ) x (25.732 + 15.732)
=414.64
0.127 expressed as a fraction = 127/1000
1/8 can also be expressed as (1 x 125) / (8 x 125) = 125/1000
The difference is 2/1000, which is 1/500
Expressing 3/8 as a decimal fraction:
We can convert 3/8 into a decimal fraction by just dividing 3 by 8 or making 3 into 8 parts.
Then, it is 3/8 = 0.375 as a decimal fraction.
Other Method::
3/8 as a Decimal :
In this we should convert the denominator into 10, 100, 1000, 10000, 100000,... to make it simple.
Now to make 8 into 1000, we multiply numerator and denominator with 125
=> (3 x 125)/(8 x 125) = 375/1000 = 0.375.
Here to say which fraction is greater from the given options, the fraction with greater numerator with same denominator or smaller denominator with same numerator.
To find the greater fraction, among the given options, make the denominators same for the options by finding the LCM of all the denominators.
7/12, 9/16, 13/20, 32/80
Now, LCM of 12, 16, 20, 80 = 240.
Then,
140/240, 135/240, 156/240, 96/240
Here
Hence, largest fraction = 13/20.
Given fraction is 3/5
Now, multiply with 2 for numerator and denominator
we get,
3/5 x 2/2 = 6/10
When we divide, 6 with 10, we get 0.6 as quotient.
Hence, 3/5 as a decimal fraction is 0.6.
5/8 = .625, 7/12 = .5833, 3/4 = .75, 13/16 = .8125
So order will be
7/12 < 5/8 < 3/4 < 13/16
So, the next number is (2 x 261 + 1) = 523.
