Question

five rational numbers between 13 upon 17 and 23 upon 57

Answer 1

Answer:

-2/3 * 3/5 + 5/2 – 3/5 * 1/6

  = -2/3 * 3/5 – 3/5 * 1/6 + 5/2             [Using associative property]

  = 3/5 * (-2/3 – 1/6) + 5/2                    [Using distributive property]

  = 3/5 * {(-4 - 1)/6} + 5/2                      [LCM (3, 2) = 6]  

  = 3/5 * (-5/6) + 5/2

  = -3/6 + 5/2

  = -1/2 + 5/2

  = (-1 + 5)/2

  = 4/2

  = 2        

Answer 2

Answer:

Rational no. between

$\frac{13}{17} and \: \frac{23}{57}$

$\frac{13}{17} \times \frac{57}{57} = \frac{741}{969} \: \: \: \: \frac{23}{57} \times \frac{17}{17} = \frac{391}{969} \\ \\ hence \: \frac{740}{969} \\ \frac{730}{969} \\ \\ \frac{720}{969} \\ \\ \frac{710}{969} \\ \\ \frac{700}{969}$
