Question

1.Find any three rational numbers between -7/11 and 2/11.
2.Find any five rational numbers between (i) 1/4and 1/5(ii) 0.1 and 0.11 (iii) -1 and -2​

Answer 1

Answer:

1. -7/11 and 2/11

WE MULTIPLY (3+1=4)TO BOTH NUMERATOR ANDDENOMINATOR

-7/11×4/4 and 2/11 ×4/4

-28/44 and 22/44

SO THE THREE RATIONAL NUMBERS ARE-

-27/44 ,-26/44 AND -25/44 ANS

2. 1/4 AND 1/5

WE MULTIPLY (5+1=6)TO BOTH NUMERATOR AND DENOMINATOR

1/4×6/6 AND 1/5×6/6

6/24 AND 6/30

LCM OF 24 AND 30

30/120 AND 24/120

SO THE RATIONAL NUMBERS ARE 25/120 ,26/120 AND 24/120.
