A) 1.375 B) 2.375
C) 0.375 D) 3.75
 
Answer & Explanation Answer: C) 0.375

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.
