Any ideas on how to solve it?

Answer 2

I've been coming up with the same answer, but my answer is not one of the answers for the question.

Answer 3

Hmmm are you sure that is how the equation is set up? Cause I get an answer that is not one of the options.

Answer 4

Yeah, it is

Answer 5

IS your answer 27/5?

Answer 6

No I did not get that.

Answer 7

First we would simplify the fraction....so we would do `1-2` and `10-3`.

\(\huge{\frac{1-2}{10-3} \rightarrow \color{purple}{-\frac{1}{7}}}\)

In which we would then have to multiply with `3`....

\(\huge{-\frac{1\times 3}{7} \rightarrow \color{green}{-\frac{3}{7}}}\)

In which we would add `12` into the equation....

\(\huge{- \frac{3}{7} + 12 \rightarrow 11\frac{4}{7} = \color{red}{ \frac{81}{7}}}\)

Answer 16

The problem here, 3⋅(1−2/10^−3)+12, is ambiguous; different people seem to be interpreting it in different ways. All that is clear to me is that y ou're multiplying the quantity within parentheses by 3 and then adding 12 to the product.

Could you use additional parentheses to clarify what is to be done within the parentheses and in what order?
