terminating decimal expansions. 35/50
​

Answer 1

Hello...

Answer:

The decimal expansion of rational number 35 by 50 without actual division is 0.7

Step-by-step explanation:

We know ,

1 / 100 = 0.01

1 / 10 = 0.1

So we will convert the given fraction , that is, 35 by 50 into the above form so that we get decimal expansion without actual division.

Given fraction is :

= 35/50  

Multiplying numerator and denominator by 2 ,

= ( 35 * 2 ) / ( 50 *2 )

= 70 / 100

Dividing both numerator and denominator by 10

= 7 / 10

This can be written as  0.7

Hence,

The decimal expansion of rational number 35 by 50 without actual division is 0.7
