Question

3 over 7=12 overd
The missing denominator is Response area.

7 over 10=n over 100
The missing numerator is

Answer 1

To solve the two problems you provided:

1. For the equation \( \frac{3}{7} = \frac{12}{d} \), you can find the missing denominator (d) by cross-multiplying:

\[
3 \cdot d = 7 \cdot 12
\]

This simplifies to:

\[
3d = 84
\]

Now, divide both sides by 3:

\[
d = \frac{84}{3} = 28
\]

So, the missing denominator is **28**.

2. For the equation \( \frac{7}{10} = \frac{n}{100} \), you can find the missing numerator (n) by cross-multiplying again:

\[
7 \cdot 100 = 10 \cdot n
\]

This simplifies to:

\[
700 = 10n
\]

Now, divide both sides by 10:

\[
n = \frac{700}{10} = 70
\]

So, the missing numerator is **70**.

In summary:
- The missing denominator is 28.
- The missing numerator is 70.
