divisions between $389$ and $390$ so each division is $\frac{390-389}{10}=0.1$
A is 8 division from $389$, so, A is $389+8\times 0.1=389.8$
similarly, C is one division behind $389$ so it is $389-1\times 0.1=388.9$
and B is $390.3$
Hint #2 is a or b so ya, and 3 is c
We have to a for its value 6, then multiply by its coefficient to then subtract.

<h2>Therefore, the expression is equivalent to 44.</h2>
