plz give me this answer plz plz plz plz any three plz kon to help karo​

Answer 1

Answer:

1) 38/11 or 3.45

2) 8/7

3) 29/21

4) $\frac{\sqrt{5} }{3} <\frac{3}\sqrt{7}$

ii) 5/18 > 17/120

Step-by-step explanation:

1) 7*7+9*3/7*7-9*3

2) i wasnt sure if its right but: 5*3-3*5+4*4/5*3-3*5-4*4

3) 5m-n=3m+4n

5m-3m=n+4n

2m=5n

$\frac{m}{n} =\frac{5}{2}$

therefore $\frac{m^2+n^2}{m^2+n^2}$

divide by n^2

$\frac{m^2}{n^2} +\frac{n^2}{n^2} /\frac{m^2}{n^2} -\frac{n^2}{n^2}$

$\frac{25}{4} +1/\frac{25}{4} -1\\=29/21$

4) wasnt so sure for this one
