Question

12. Complete the comparison: 3+7>?

O A. 7 + 3
O B. 9 + 4
O C. 10-2
O D. 8 +2.

Answer 1

Answer: C. 10-2

3+7 = 10
So you need to find which value is less than ten


A is wrong because 7+3= 10 and 10 is not less than 10
B is wrong because 9+4 = 11 and 11 is not less than 10
D is wrong because 10-2 = 10 and 10 is not less than 10

C is right because 10-2 =8 and 8 is less than 10

Answer 2

For this case we must complete the following expression:

`3 + 7>`

We add the terms on the left side of the inequality:

`10>?`

We must complete the right side of inequality with one of the following options:

Option A:

`7 + 3 = 10`

We have to:

`10> 10`

It is not fulfilled!

Option B:

`9 + 4 = 13`

We have to:

`10> 13`

It is not fulfilled!

Option C:

`10-2 = 8`

We have to:

`10> 8`

Is fulfilled!

Option D:

`8 + 2 = 10`

We have to:

`10> 10`

It is not fulfilled!

ANswer:

Option C:

`10> 8`
