Question

Type the correct answer in the box. Use numbers instead of words.
An equation with a missing numerator is shown.
?/12 - 1/3= 7/12

What is the missing numerator?

Answer 1

To solve the equation \(?/12 - 1/3 = 7/12\), we first need to express \(-1/3\) with a denominator of 12.

The fraction \(-1/3\) can be converted:

\[
-1/3 = -4/12
\]

Now, substitute this into the equation:

\[
?/12 - 4/12 = 7/12
\]

Next, we can add \(4/12\) to both sides:

\[
?/12 = 7/12 + 4/12
\]

Now, add the fractions on the right side:

\[
7/12 + 4/12 = 11/12
\]

So we have:

\[
?/12 = 11/12
\]

This means:

\[
? = 11
\]

Thus, the missing numerator is:

11
