answer the question given

Answer 1

Answer:

1) 2/7and3/4= 2/7, 2/8, 2/9.........3/4

2) 328/400= 0.8225

3) 1.27= 127/100

4) (3+√3) (2+√2)

= (4.73 2050 81) (3.4 1 4 2 1 3 5 6)

= 4.73 2050 81 *3.4 1 4 2 1 3 5 6

= 16.1 56232 (answer)

5) 5/7= 5.7(and)

Answer 2

Answer:

Step-by-step explanation:for question 1

First take the Lcm of 7&4 i.e 28

Then multiply 2 by 4(as 7*4=28)we get 8\28

And multiply 3by7(as4*7=28)we get 21\28

Now we can easily find 4 rational no.between 8\28 and21\28

i.e 9\28,10\28,11\28,12\28,13\27,14\28,15\28,16\28,17\28..till 27/28
