Question

Which pair of equations has 9 as the missing number?(1 point)
Responses

6 x ___ = 42; 42 ÷
___ = 6
6 x ___ = 42; 42 divided by ___ = 6

___ x 3 = 27; 27 ÷
___ = 3
___ x 3 = 27; 27 divided by ___ = 3

4 x ___ = 32; 32 ÷
4 = ___
4 x ___ = 32; 32 divided by 4 = ___

___ x 8 = 64; 64 ÷
8 = ___

Answer 1

Let's examine each pair of equations to find out where 9 will fit as the missing number:

1. **6 x ___ = 42; 42 ÷ ___ = 6**
- For the first equation: 42 ÷ 6 = 7 (so the missing number is 7, not 9).

2. **___ x 3 = 27; 27 ÷ ___ = 3**
- For the first equation: 27 ÷ 3 = 9 (the missing number is 9).
- For the second equation: 9 x 3 = 27 (which also holds true).

3. **4 x ___ = 32; 32 ÷ 4 = ___**
- For the first equation: 32 ÷ 4 = 8 (the missing number is 8, not 9).

4. **___ x 8 = 64; 64 ÷ 8 = ___**
- For the first equation: 64 ÷ 8 = 8 (the missing number is 8, not 9).

The only pair of equations where the missing number is 9 is:

**___ x 3 = 27; 27 ÷ ___ = 3**.
