Question

1. Write an Expression with a Value of 12. it should contain four numbers and two different operations.

Answer 1

Answer:

1)  $2\times2+4+4=12$  

2 )Below statements are true

1.  7 + 3 ×(2 + 4)= 25

2. $\frac{8^2}{4\times8}=2$

3. 16 + 8-(5×2)= 14

Step-by-step explanation:

1) To write an expression with a value =12 it should contain four numbers and two different operations.

  $2\times2+4+4=12$  

2)  Place Parentheses,if needed, to make each statement true.

1. 7 + 3×2 + 4= 25

In this statement one parentheses is missing i.e. bracket

New statement → 7 + 3 ×(2 + 4)= 25

7 + 3 ×2 +3× 4= 25

7 + 6 + 12= 25

25=25  now, the statement is true.

2.  8 (a Two Above the 8) Divided by 4 x 8 = 2

This statement (a Two Above the 8) means $8^2$

so, $\frac{8^2}{4\times8}=2$

      $\frac{64}{4\times8}=2$

      $2=2$

The statement is true.

3.  16 + 8 - 5×2 = 14

The statement is true when we solve by BODMAS

i.e.  16 + 8-(5×2)= 14

      16 + 8-10= 14

     24-8=14

        14=14  statement is true

Answer 2

1) 2*2+4+4=12
2) 1. 7 + (3 x 2) +25
    2. 2/8 divided by (4x8) =2
    3. 16+8 -(5x2)=14


hope this help...
