a)
First term = 7/5 ÷ - 9/7
= 7/5 × (- 7/9)
= - 49/45
Second term = - 9/7 ÷ 7/5
= - 9/7 × 5/7
= - 45/49
Both results are negative numbers. The first one (- 49/45) is more negative than the second one (- 45/49) and thus the first number is less than the second number.
∴ 7/5 ÷ - 9/7 < - 9/7 ÷ 7/5
b)
Let the required number be x
Then, 7/9 ÷ x = 7/9
⇒ 7/9 × 1/x = 7/9
⇒ 1/x = (7/9) / (7/9)
⇒ 1/x = 1
⇒ x = 1
∴ the blank will have 1
