3 over 7=12 overd

Question

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.
