Question

Please give me answer fastt​

Answer 1

Step-by-step explanation:

39.

descending order of ½, ⅘, ³/2, ⁷/3

now LCM of 2,5,2,3 = 30

so ½ = 15/30

⅘ = 24/30

³/2 = 45/30

⁷/3 = 70/30

therefore,

70/30 , 45/30 , 24/30 , 15/30

⁷/3 , ³/2, ⅘ , ½

40. 9x -5 = 13

LHS,

9 X 2 - 5

18 - 5

13

RHS = 13

because, LHS = RHS

so, yes x = 2 is the solution of 9x -5 = 13

Answer 2

Answer:

39. 7/3, 3/2, 4/5, 1/2

40. Yes

Step-by-step explanation:

40. 9 × 2 - 5 = 13

18 - 5 = 13

13 = 13

39. 7/3 × 10/10 = 70/30

3/2 × 15/15 = 45/30

4/5 × 6/6 = 24/30

1/2 × 15/15 = 15/30
