$${\frac{{\mathtt{4}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{3.14}}$$

We all know that 3.14 is equal to 22/7

so, we dont have to after all try to make 4/3 a decimal, cuz you can make 3.14 a fraction

$$\left({\frac{{\mathtt{4}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{22}}}{{\mathtt{7}}}}\right)$$

no cross cancelling can be done sadly

so 4*22=88

3*7=21

now, its 88/21

if you however want to try to make me not be lazy and make me convert it to a mixed number fraction:

21 would go in 88 4 times

21*4=84 

4 additional pieces of 88 are included

overall answer:

4 4/21 or 88/21

I will give you your 3 points  TitaniumRome  but  3.14 is not exactly equal to 22/7

 

They are only approximately equal to each other.

Look

$${\frac{{\mathtt{22}}}{{\mathtt{7}}}} = {\mathtt{3.142\: \!857\: \!142\: \!857\: \!142\: \!9}}$$ 

 

Real answer  4.186 repeater

$${\frac{{\mathtt{4}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{3.14}} = {\frac{{\mathtt{314}}}{{\mathtt{75}}}} = {\mathtt{4.186\: \!666\: \!666\: \!666\: \!666\: \!7}}$$

 

Your answer.

$${\frac{{\mathtt{88}}}{{\mathtt{21}}}} = {\mathtt{4.190\: \!476\: \!190\: \!476\: \!190\: \!5}}$$
