Answer 1

c and d are the correct answers !

Answer 2

Option C and D!

Explanation:

• Option C because:-

When 9 is placed in the box after 7, we get:-

7 ÷ 9 =
`(7)/(9)` which is correct!

7 ÷ 9 can also be written as
`(7)/(9)`. So, this Option is right since the equation is correct when 9 is placed in the box!

• Option D is also correct because,

When we place 9 in the box before
`(1)/(9)`, we get:-

9 ÷
`(1)/(9)` = 81

9 ÷
`(1)/(9)` equals 9 x 9 (take the reciprocal of
`(1)/(9)`)

9 x 9 equals 81 which means the equation is correct when 9 is placed in the box!
