Question

8. Divide the sum of 65/12 and 12/7 by their difference.
9. Find any 10 rational numbers between
li) -1/5 and 1/2
i) 2/8 and 3
10. Verify 5/6 - (2/7 + 3/8) = (5/6 - 2/7) + 3/8.​

Answer 1

Answer:

sum of 65/12+12/7=599/84

differrence of 65/12-12/7=311/84

divide 599/84÷311/84

599/311

Answer 2

Answer:

8. (65/12+12/7) ÷ (65/12-12/7)

LCM = 84

65/12 = 455/84

12/7 = 144/84

Sum = 455 + 144 /84 = 599/84

Difference = 455 - 144 / 84 = 311/84

Division = 599/84÷311/84 = 599 /84 × 84/311

= 599 / 311 = 1 288/311
