Answer»

i. (1 × 7) = ( [ ] × 1)

1 x 7 = 7,

7 x 1 = 7

so, (1 x 7) = ( 7 x 1)

ii. (5 × 4) > (7 × [ ] )

5 x 4 = 20, 7 x ………… must be less than 20.

7 x 2 = 14

so, (5 x 4) > ( 7 x 2)

iii. (48 ÷ 3) < ( [ ] × 5)

48 – 3 = 16,

5 x 4 = 20

5 x 3 = 15

16 > 15 and 16 < 20

so, (48 + 3) <(4 x 5)

iv. (0 + 1) > (5 × [ ] )

0 + 1 = 1,

5 x 1 = 5

5 x 0 = 0

1 < 5 and 1 > 0

so, (0 + 1) > (5 x Q)

iv. (35 ÷ 7) = ( [ ] + [ ] )

35 ÷ 7 = 5,

3 + 2 = 5

so, (35 + 7) = (3 + 2)

v. (6 – [ ] ) < (2 + 3)

6 – < 2 + 3 = 5

5 > 6 – 2

so, (6 – 2) < (2 + 3)
