Answer: 0
Step-by-step explanation:
Conversion of Mixed fraction to improper :
, where a, b, c are integers and not equal to zero.
The given expression :
..(i)
Here ,
..(ii)
...(iii)
Now substitute (ii) and (iii) in (i) , we get
![\dfrac{13}{4}-\dfrac{8}{3}=\dfrac{13\times3-8\times4}{4\times3}\\\\=\dfrac{39-34}{12}\\\\=\dfrac{7}{12}=0.583333333333\approx0 [\text{Nearest given option}]](https://tex.z-dn.net/?f=%5Cdfrac%7B13%7D%7B4%7D-%5Cdfrac%7B8%7D%7B3%7D%3D%5Cdfrac%7B13%5Ctimes3-8%5Ctimes4%7D%7B4%5Ctimes3%7D%5C%5C%5C%5C%3D%5Cdfrac%7B39-34%7D%7B12%7D%5C%5C%5C%5C%3D%5Cdfrac%7B7%7D%7B12%7D%3D0.583333333333%5Capprox0%20%5B%5Ctext%7BNearest%20given%20option%7D%5D)
Hence the best estimate for the give expression would be 0.
